When Understanding the Problem Has Not Changed It

Some couples begin therapy unsure why their relationship has become so difficult. Others arrive with considerable insight. They may recognise the same argument returning, know who usually pursues the conversation or becomes quiet, and understand something about the histories that have shaped these responses. They may already have spent a long time talking, reading or trying different ways of handling things.

Understanding can matter, but what we understand afterwards is not always available to us while the relationship is under strain. A person may know that they become anxious when something feels unresolved, yet still experience the need to resolve it immediately when it happens again. Someone may understand why they withdraw from conflict but only recognise that they have shut down once the conversation is already over.

Psychological couples therapy therefore involves more than producing another explanation for why a relationship has become difficult. The work is to develop an understanding that can increasingly be used: to notice how a difficulty begins, what happens to each person as it develops, what each response comes to mean to the other, and where there may be enough room for something different to happen.

That understanding begins through assessment, but it continues to develop through the work itself. This article describes how I approach couples work within an integrative psychological practice. The balance of reflection, practical work and therapeutic methods will vary with the couple and may differ across practitioners.

Couples come to this work across cultures, sexual orientations, gender identities, ages and professional backgrounds. Some are beginning a relationship; others have shared much of their adult lives. One or both partners may be neurodivergent. These aspects of life can influence what happens between partners, although their significance needs to be discovered together.

What Happens at the Beginning of Couples Therapy?

Assessment gives each partner space to describe what has brought them, what they hope might change and what they value in the relationship. It also considers the pressures around the couple and whether joint work is suitable and sufficiently safe. An initial aim may be quite specific, such as addressing arguments about parenting, or more exploratory, such as understanding a growing distance neither person can readily explain.

The practical arrangements need to be clear too. At the outset, couples should understand confidentiality and its limits, how any individual contact would be handled, and what would happen to information shared separately. These arrangements should be discussed with the psychologist rather than assumed to be the same in every service.

As the work develops, sessions may involve reflecting on experiences at home, attending to an interaction as it happens, or exploring a different response together. Where useful, partners may agree something to notice or try between sessions. Reviewing whether the work is helping includes hearing from both people and reconsidering goals, pace or approach when needed.

Building a Shared Understanding of the Relationship

Each person brings a history into the relationship. Experiences of family, care, independence, conflict, belonging, previous relationships and significant life events may matter. Culture, language, neurodevelopment, trauma, health and the circumstances in which the couple are living may also change how particular experiences are understood.

But couples therapy is not simply two individual histories placed beside one another.

Something has also developed between the partners.

A person who becomes anxious when something feels unresolved may try harder to continue the conversation. Their partner finds the intensity difficult and becomes quieter. The reduction in response increases the first person's anxiety, while the increased urgency makes the second person want more distance. Neither response exists on its own for very long. Each begins to alter the conditions to which the other person is responding.

Understanding this mutual influence does not mean that responsibility or impact are equal. Coercion, intimidation and abuse require a different assessment; describing them as a shared communication cycle can obscure who is being harmed and who needs to take responsibility.

In psychological practice, the developing map we make of this is often called a formulation. It brings together what tends to happen, what each partner notices, the meanings they make of one another's responses, what they may be trying to protect or restore, and how the sequence gathers momentum.

It also needs to include what is working. Similar conversations may go differently under some conditions. There may still be humour, warmth, practical care or cooperation between the partners. They may already have found their way through difficult periods before. There may be moments when repair happens more easily, or occasions when one person responds quite differently from the role they are usually given.

These exceptions matter because they show that the difficulty is not simply a fixed property of either person. Someone usually described as avoidant may remain engaged when they feel less pressured. A partner experienced as demanding may respond differently when they trust that an issue will genuinely be returned to. Instead of asking only, What kind of person is my partner?, therapy can begin asking: Under what conditions does this way of relating become more or less likely?

A formulation is therefore not a description of what is defective about the couple. It is a developing understanding of the relationship, including its difficulties, resources, histories and wider context. It also needs to remain provisional. If it stops making sense to one or both partners, it needs to be reconsidered.

Working With What Happens in the Room

Couples naturally spend time telling the psychologist about what happened at home. Sometimes something equally useful happens while they are telling us.

One partner begins explaining and the other corrects a detail. Someone becomes quieter. A question produces an unexpectedly defensive answer. One person begins looking towards the psychologist for confirmation instead of towards their partner. A conversation that had been thoughtful suddenly becomes much harder.

But something has just happened between them.

The psychologist can slow the interaction down and become curious about what changed. Perhaps one person heard criticism where the other intended explanation. Someone may have become frightened that acknowledging an impact means accepting an account they do not recognise. Another may have reached the point where they can no longer think clearly enough to continue.

Something that looks defensive may include fear of being blamed. Urgency may have developed because quieter attempts to connect repeatedly felt unnoticed. Silence might involve overload, uncertainty, restraint, anger, a need to think or an attempt to stop the interaction escalating. Understanding these meanings can help us respond more accurately. It also leaves room to name behaviour that has been hurtful or unacceptable and consider what needs to change.

We cannot know its meaning simply from how the behaviour looks.

That matters because this is often where insight becomes more usable. Knowing that you become quiet when overwhelmed is different from recognising the moment your thinking has begun to narrow. Knowing that reassurance matters to you is different from noticing the fear that has suddenly made reassurance feel urgent.

The therapeutic task is not to prevent every familiar reaction. It is to make the point at which the sequence begins to take over easier to recognise, so there may be a little more room to choose what happens next.

This does not require everyone to become more emotionally expressive. Some people need time before they know what they feel. Some think things through privately. Some communicate care more readily through action. Composure, practical support and restraint can all have meaningful places within a relationship.

What matters is whether partners have enough access to what is happening to make useful choices. Sometimes the relevant information is emotional. Sometimes it involves thoughts, bodily sensations, sensory overload, uncertainty, practical need, or simply recognising that a conversation has reached the point where continuing is no longer helping either person.

In my practice, we consider which ways of working help both partners participate, including when they need different kinds of time, structure or communication.

The experience of feelings becoming harder to recognise or express within a valued relationship is explored more fully in Can You Feel Safe Being Yourself?.

Trying Changes Within and Between Sessions

A shared understanding becomes useful when the couple can begin to discover what happens if part of a familiar sequence changes.

The difference may initially be small. Someone notices that they are trying to resolve everything immediately and can communicate that they are becoming frightened rather than continuing to increase pressure. A partner who usually leaves the conversation can say that they need time while being clearer about how and when they intend to return. Someone can acknowledge the impact of something before moving immediately into intention or explanation.

These can become collaborative experiments. Does a pause with a clear return point reduce anxiety? Does acknowledging an impact make explanation easier to hear, or does something else become difficult? What happens next helps us consider whether the change is useful and what still needs attention.

At other times, what needs to change is practical. There may need to be clearer agreements around family involvement, finances, household responsibilities, parenting, privacy or time together.

If one partner is repeatedly left to organise the household, for example, understanding why requests become tense may help, but the workload still needs attention. A useful agreement might involve taking responsibility for noticing and completing a task, including its planning, rather than waiting to be asked. The couple can then review whether the burden has actually shifted. Continued frustration may tell us that the agreement has not changed enough in daily life.

Understanding and change develop alongside one another. We make sense of what is happening, try something different, notice what follows and revise our understanding again.

Working With Intimacy, Hurt and Repair

Intimacy is another area where knowing the problem does not necessarily change the experience of it. Physical affection, sex, emotional conversation, companionship, shared activity, humour, practical care and privacy can all carry meanings of closeness.

The important question is not only what form of intimacy does each person prefer? It is also: What has this particular form of closeness come to mean between us?

A reach for affection may be experienced as connection by one person and expectation by the other. Asking to talk may represent closeness, reassurance, pressure or exposure. Giving somebody space may feel respectful to one partner and like withdrawal to another. The same behaviour can therefore invite very different experiences.

Therapy can help couples explore what has become difficult to offer or receive, and whether closeness has become entangled with rejection, reassurance, obligation, pressure or unresolved hurt. The task is not to decide whose preferred form of intimacy is healthier. It is to understand what each person is responding to and what may need attention before intimacy can begin to feel different.

Each person's consent and freedom to decline remain fundamental. Wanting closeness does not create an entitlement to sex, affection or disclosure. Partners may also differ in how important sexual activity is to them; its frequency alone cannot tell us how connected or satisfied they feel.

Where there are specific psychosexual difficulties requiring specialist assessment or treatment, different or additional professional support may sometimes be appropriate.

Repair can carry similar complexity. What remains active after a hurtful event may not be only the original event. It may also include how the hurt was responded to afterwards, what happened during earlier attempts to discuss it, whether anything changed, and what later experiences have added to its meaning.

An injury can therefore accumulate a history of its own.

Psychological work can help separate some of these layers. This may allow a couple to recognise where something genuinely has changed while also understanding why part of an earlier injury remains sensitive.

Partners do not necessarily need the same thing at the same moment. One person may need their experience recognised before they can make use of context. Another may need to know that acknowledging impact does not require them to abandon their own experience.

Where trust has been breached, repair may require acknowledgement, changed behaviour and agreements that are respected over time. A partner's need for accountability cannot always be resolved through reassurance or a different interpretation of the event. There is no single repair sequence that every couple has to follow, and neither forgiveness nor renewed closeness can be required as proof that therapy is working.

Culture, Language and Social Context Change the Meaning

Culture is not an additional topic to consider after the psychology has already been understood. It can change what behaviour itself means.

Expectations around family, privacy, money, independence, gender, responsibility, emotional restraint, parenting and care develop within wider social and cultural contexts. Language matters too. Some experiences are easier to articulate in one language than another. Particular words may carry emotional or relational meanings that do not move neatly between languages. A conversation may also feel different depending on which partner is speaking in a first, second or less familiar language.

Culturally responsive couples work therefore requires curiosity rather than assumptions. Something should not automatically be explained by culture simply because partners have different backgrounds. Equally, leaving cultural and social experience out can make the psychological understanding less accurate.

Power matters here as well. One partner may have migrated and become more dependent on the other's established life. One may experience racism or marginalisation that the other does not. One person may repeatedly carry more of the work of translation, adaptation or negotiating with family. An apparently equal decision can therefore carry very different consequences.

These differences need to be recognised without reducing either person to a cultural category, or assuming that every intercultural difficulty is fundamentally about culture.

Differences can also be resources. Partners may have developed ways of moving between languages, sharing traditions or making a life that neither inherited unchanged. Couples with a shared cultural background can still differ substantially in family expectations, faith, class or experience. Therapy needs to remain interested in what these particular partners have made together.

For LGBTQ+ couples, questions of recognition can enter everyday decisions about family contact, public affection, privacy or whose understanding of the relationship is accepted. Experiences of homophobia or transphobia may affect one or both partners. One person may be open about their identity in settings where the other is not. The work may involve understanding the consequences for each person, including safety and belonging, without assuming that disclosure is always the appropriate goal. Sexual orientation or gender identity may be central to a difficulty, or simply part of the couple's life while they seek help with something else.

Age and life stage can matter in similarly specific ways. Partners may be negotiating different timelines for parenting, career change, retirement or caring for relatives. Professional life can shape time, financial dependence and the capacity available at home. Being highly capable at work does not necessarily make a difficult conversation with a partner easier, and neither partner's occupational status makes their account of the relationship more authoritative.

Either partner may feel that the psychologist understands one person's language or background more easily than the other's. Cultural similarity does not guarantee understanding, and difference does not prevent it. These experiences need room for discussion, including when the psychologist has missed something important.

For multilingual couples, sharing a language with one partner should not turn the psychologist into that person's interpreter or cultural representative. Both people need to remain participants in the psychological work.

How attention to context can change the understanding and direction of therapy is explored in Culturally Responsive Therapy: What Changes When Therapy Fits the Person?.

Trauma and Neurodivergence May Matter Without Explaining Everything

Earlier traumatic experiences can affect what feels threatening, exposing or difficult to trust within a current relationship. Neurodivergence may be relevant to communication, attention, sensory experience, predictability, organisation, recovery following intense interaction, or how emotional and relational information is signalled, noticed and processed.

Recognising these contexts can reduce moral interpretations of behaviour. Something experienced as indifference may involve information being communicated or registered differently. A need for predictability may have been understood as inflexibility. Time required to process an intense interaction may appear like deliberate withdrawal from the outside. These possibilities need exploring with both partners rather than being assumed from a diagnosis.

A diagnosis should not become a shortcut that closes down curiosity about the relationship. One or both partners may be neurodivergent, and neither person's way of processing should automatically become the standard against which the other is judged. The work may benefit from a more explicit structure, clearer language, sensory adjustments or additional time to process, according to what each person finds useful.

A scoping review by Stafford (2023) found limited empirical research evaluating relationship-counselling approaches involving autistic adults. Adaptations need to be considered collaboratively, with attention to whether they make the work more accessible and useful for both partners.

The same principle applies to trauma. Trauma-informed work takes earlier experiences seriously while remaining interested in what is happening in the present relationship.

Context should sharpen our understanding rather than replace it.

When Partners Want Different Things From Therapy

Couples often begin therapy with different levels of readiness and different hopes for the work. One person may have considered therapy for months while the other has only recently realised how serious the difficulty feels. One wants more closeness. Another primarily wants fewer arguments. One partner may not yet know whether they want the relationship to continue.

Early work explores where these aims overlap and whether there is enough shared purpose for joint work to be meaningful. Partners can begin with different levels of motivation, but both need enough willingness to participate and consider what therapy may ask of them. The psychologist cannot undertake the work on behalf of a partner who does not want to take part.

Goals may change as the work develops. For some couples, therapy supports rebuilding the relationship. For others, it brings greater clarity about separation. Therapy is not successful only when two people remain together, and the psychologist does not make that decision on the couple's behalf.

Holding a Therapeutic Relationship With Two People

Couples therapy involves several therapeutic relationships at once. Both partners need to experience the work as sufficiently trustworthy, respectful and useful to remain engaged.

This does not mean that each person will feel equally understood in every moment. There may be occasions when one person's experience requires more space, when an impact needs to be named, or when a difference in power cannot responsibly be treated as though it were neutral.

But it matters if one partner increasingly experiences the psychologist as naturally siding with, believing or understanding the other.

Those experiences need to be speakable.

The therapeutic alliance in couples work is therefore not simply about whether each individual likes or trusts the psychologist. It also concerns whether both people can experience the space as one in which their perspective can be considered without the work gradually becoming organised around one person's version of the relationship.

Research in couple and family therapy suggests that the quality and balance of this alliance are associated with outcome (Friedlander et al., 2018). A strong therapeutic relationship with both partners does not require equal agreement with everything either person says. The psychologist needs to remain engaged with both people while continuing to hold the relationship, wider context, power and safety in view.

Safety, Power and Suitability

There are limits to understanding relationship difficulty primarily as a shared cycle. Where there is coercive control, intimidation, abuse, fear about what may happen after a session or significant concern about safety, describing what is happening simply as a pattern to which both partners contribute can conceal rather than clarify the problem.

Where coercive control or fear of retaliation is present, joint work can increase risk and should not proceed as ordinary couples therapy. Suitability assessment needs opportunities to consider safety privately with each partner, with confidentiality arrangements explained beforehand. Clinical guidance on couple therapy and intimate partner violence discusses why separate, private assessment matters. Attending a session together is not itself evidence that both people can speak freely.

There may also be circumstances where individual psychological therapy, medical or psychiatric care, substance-use treatment or specialist psychosexual support is needed before, alongside or instead of couples therapy.

What Does the Evidence Tell Us?

A meta-analysis by Roddy and colleagues (2020), drawing on 58 studies, found improvements in relationship satisfaction, communication, emotional intimacy and partner behaviour. These findings support couples therapy as a useful intervention for relationship distress. They describe outcomes across study participants and cannot predict what will happen for a particular couple.

Research on couples therapy also needs to be distinguished from evidence for a specific adaptation or combination of methods. Broad findings cannot establish that an approach has been equally evaluated across every cultural context, relationship or neurotype.

Within my integrative practice, research evidence, psychological theory and therapeutic approaches inform the work alongside the couple's experience and our developing formulation. We consider how these perspectives fit what is happening, attend to what emerges between us, and remain willing to revise our understanding. Each partner's feedback and changes in daily life help us judge whether the work is useful.

What Might Change Through Couples Therapy?

Couples understandably hope that therapy will stop difficult arguments or restore how the relationship once felt. Sometimes conflict reduces, trust rebuilds or intimacy becomes easier.

Other changes can be quieter but still significant.

A familiar pattern becomes recognisable before it has fully taken over. One partner can ask for time without leaving the other unsure whether they will return. An impact can be acknowledged without somebody immediately losing access to their own perspective. A difficult conversation can be paused when neither person is able to hear much more, and genuinely returned to later.

Something repeatedly understood as a personality flaw may become more understandable and therefore more workable. The couple may become clearer about which differences need negotiating, which require genuine change and which parts of one another do not need fixing.

Culture, temperament, neurodivergence and different needs do not disappear because therapy has gone well. Nor should they.

What may develop through therapy is greater relational flexibility: recognising what is happening earlier, understanding enough of its meaning, and having more than one possible way of responding when familiar difficulties return.

Over time, an understanding that once arrived mainly afterwards may become available sooner, while an old pattern is beginning to gather momentum and there is still some possibility of responding differently.

Considering Couples Therapy

An initial assessment offers time to understand the relationship together and consider whether joint psychological work is appropriate for what each of you needs.

I offer online psychological therapy for couples in English, Cantonese and Mandarin.
