Avoidant Attachment and Trauma Therapy: A Conversation with Robert T. Muller

Written by Roland Bal

I sat down with Robert T. Muller, PhD — a trauma psychologist at York University in Toronto and author of Trauma and the Avoidant Client and Trauma and the Struggle to Open Up — to talk about something every trauma therapist eventually runs into: the client who needs help but cannot seem to let it in. Why does opening up feel so dangerous for some people, and what does the work actually look like when a client's whole strategy has been to keep their pain out of reach?

Why Avoidant Clients Struggle to Open Up

Muller's central interest is the avoidant client, partly because, as he points out, there is comparatively little written about how to actually work with someone who is reluctant to engage. The difficulty for these clients is not simple stubbornness. It is a pattern of self-protection that runs in two directions at once. On one side, they are protecting themselves from feelings that are genuinely overwhelming — feelings that can pull them back into painful memories and flashbacks. On the other, they are protecting their relationships.

This second part is easy to miss. Talking honestly about a difficult parent can feel like complaining, like disloyalty, like breaking a family secret. Avoidance is a survival strategy, not a character flaw. When you grow up in a home where you have to act as if things are fine when they are not, you learn to tell yourself stories that are not quite true — and those coping strategies work, for a while. They tend to break down later, when life asks something new of the person: commitment, marriage, children, illness, loss. The old ways of coping stop working, and that is often what finally brings someone into therapy.

Meeting the Client Where They Are

Muller is emphatic that the work starts not with the trauma but with the person's own sense of what is wrong. Many clients do not arrive announcing a trauma history — they simply know that something is not working, that they are upset for reasons they cannot name, that relationships keep going wrong. So the first task is to find, together, what they are actually suffering with and how they would like to see themselves different by the end. Getting concrete helps: walk me through a day in which this change has happened — what does it look like, what feels different?

From there, the trauma themes tend to surface on their own. Muller described listening for what he calls trauma fragments — small comments a client drops along the way, often told lightly or even as a joke, that carry far more weight than their telling suggests. He gives the example of a man who recounted, almost as a funny anecdote, that his mother had tried to abort him. Told as comedy, it is in fact a profoundly sad story. The therapist's job is not to pounce on it but to notice it, file it away, and gently bring it back when related themes — rejection, not being wanted, not mattering — resurface later. Brought back into the room, these fragments begin to connect into themes the client starts to recognise as their own.

Resistance as Ambivalence, Not Refusal

One of the most useful reframes in the conversation concerned resistance. If a client keeps coming back week after week to tell you they do not need therapy, Muller asks the obvious question: why are they spending the time, money, and effort to keep showing up? There must be a part of them that recognises something. Drawing on John Bowlby, he describes the client as genuinely divided — a part that yearns to feel better and be understood, and a part that is afraid, and the fear holds them back.

The clinical implication is gentle but precise. The fighting, guarded side is not the enemy; it has worked for the person, and you do not try to strip it away. Instead you listen for the vulnerable, hurt part underneath without making a show of having found it. With avoidant clients in particular, anger often comes first because it is the easier emotion to reach — but underneath the anger sit more vulnerable feelings, only a short step away.

The Four Attachment Styles

Muller laid out the four attachment patterns through a simple image: a child who falls off a bicycle and looks up at the parent. That look, in Bowlby's terms, is an attachment signal. How the parent responds shapes the pattern. A parent who offers no touch and no acknowledgement — "dust yourself off, you'll be fine" — teaches the child to turn away from their need for comfort and toward the purely cognitive; this is the root of avoidant attachment. A parent who becomes more distressed than the child, producing role-reversal, can foster a preoccupied style, where the person stays caught up in their attachment hurts well into adulthood.

The most difficult of the insecure patterns is disorganized attachment, where the child both moves toward and pulls away from the parent, having no coherent strategy for managing the pain — often because the parent's own difficulties make consistent care impossible. Muller was careful to add the encouraging part: roughly two-thirds of the general population fall into the secure pattern. A secure attachment does not mean a life without suffering or depression; it means the person tends to regulate more readily and is usually more quickly receptive to therapy. The parent in the bicycle example did not need to be perfect — only good enough to help the child settle and recover.

Troubled attachment is a natural outcome of challenging life experiences or trauma.

The Therapy Relationship as the Place of Repair

Perhaps the richest part of the conversation was about what happens in the room between client and therapist. When the therapist shows up ten minutes late, or the client feels disappointed or quietly angry — these micro-conflicts are not interruptions to the work, they are the work. Noticing them, naming them, and wondering aloud with the client about what is happening between the two of you can be remarkably powerful, especially for someone who reflexively makes excuses for everyone who has ever hurt them.

Muller's advice to therapists working with avoidant clients was to go slowly, to watch their own countertransference, and to beware the rescue fantasy — what he half-jokingly calls Savior syndrome — that gets frustrated when the client does not improve on the therapist's timeline. Above all, let the client do the work. When they shrug and say "I don't know," resist the urge to immediately supply another question; instead, give them a moment to sit with the small, tolerable anxiety of not knowing, and see what surfaces. This is where the relationship itself becomes a corrective experience — a slow, attuned restoration of safety that is, in practice, what nervous system regulation looks like between two people.
