First, when the urge to over-function appears, offer support once and then stop. Say what you can provide, name your limit, and let the partner respond. That single boundary interrupts the escalation before it requires a retreat. Second, after any difficult exchange, write down four things: the trigger, the story you told yourself about it, the physical sensation you noticed, and what you actually did. Reviewing that sequence over several weeks makes the approach-withdrawal switch visible earlier, which is when it is easiest to redirect. A small, specific promise kept on time—"I'll text you by nine"—builds more relational trust than a sweeping commitment to be more open. Consistency in small moments gives both people evidence that contact can survive discomfort.
