Couples do not come to therapy because everything is going well. They arrive when something has already broken down, either through a specific event or through a gradual erosion. What they are usually asking for is to get back to how things were.

But this is where the problem sits. The version of the relationship they are trying to restore is often the very structure that made the crisis inevitable. It held together for a time, but only within limits that were never fully tested. What looked like stability was a system that could not sustain pressure indefinitely. The relationship as it was before the crisis is the problem. It was structurally vulnerable.

The crisis exposes that vulnerability.

Something in the relationship can no longer continue in the same way. The usual ways of managing difference, conflict, and tension reach their limits. What was previously contained begins to spill over. What was avoided becomes unavoidable.

The underlying structure becomes visible because it can no longer hold itself together. Patterns that were manageable at lower levels of intensity become unworkable. What was previously tolerated becomes intolerable. The relationship cannot return to its prior state without recreating the same conditions that produced the crisis. The structure itself has to change.

This is where the tension sits in therapy.

On the one hand, the couple wants relief from the instability. On the other, the work requires remaining within that instability long enough for something different to emerge. This is second-order change, a shift in the logic that shapes experience and interaction. When the pattern remains intact, even if behaviour adjusts, the same experience reappears. That is first-order change (Watzlawick, Weakland, & Fisch, 1974).

Intervention therefore does not aim to remove instability, but to work within it. The task is to prevent collapse while also preventing a return to the old pattern. The system has to be held in a position where it cannot continue as before, but also does not disintegrate.

This is where reorganisation becomes possible.

New forms of interaction begin to appear, often tentatively at first. A different response in a familiar moment. A shift in how difference is handled. A break in the usual sequence. These are not improvements added to the old structure. They are the early signs of a different organisation taking shape.

The tension and distress of the crisis are not incidental. They are the conditions that make new responses possible.

Growth does not come from restoring what was there before. It comes from moving through a period where the old way no longer works and a new one has not yet formed. That space is uncomfortable. It is uncertain. It often feels like things are getting worse rather than better.

It is also the only space in which something genuinely different can emerge.
