In couple therapy, disruption is not about blame, judgement, or making a point. It is about interrupting a pattern. It is not moral, educational, or insight-based. It is structural.

Couples do not stay stuck because they lack understanding. Most know exactly what isn’t working. They can explain it in detail. Insight may increase awareness, but on its own it rarely changes what happens in the moment. Patterns persist because they are enacted, not because they are misunderstood.

Disruption targets the enactment itself.

When a familiar conversational or interactional sequence is interrupted, what would normally happen is prevented from happening. The autopilot does not get to repeat what has been done a thousand times before. In systemic terms, this is referred to as perturbation.

When that script is interrupted, the system cannot stabilise itself in the usual way. The dance is disrupted. Friction increases. Intensity rises. Pressure is created. Like a river blocked from following its usual course, the system experiences distress — but more importantly, it is forced to reorganise.

This is the critical point.

Change does not come from explaining the pattern while it continues to run. It comes from preventing the pattern from running at all. When the familiar move is no longer available — when escalation, withdrawal, correction, or shutdown are interrupted — something else has to emerge. The couple has to find a new way of engaging, even if only momentarily.

Disruption is experienced as uncomfortable, often for everyone involved — including the therapist. It raises intensity in the room. It creates uncertainty. But that intensity is not a failure of the intervention. It is evidence that the system has been pushed out of its default organisation.

Without disruption, therapy risks becoming descriptive rather than transformative. With disruption, the system is given no choice but to adapt. That is why interruption matters. Not as technique, not as confrontation, but as the structural condition that makes reorganisation possible.
