Case. In any tense moment one partner goes silent and leaves; the other is left feeling abandoned.
Model. Stonewalling is not indifference but overload: the system defends itself by shutting off. The problem — the ticket stays open and resurfaces.
Protocol. Agree on a pause with a promise to return: “I need 20 minutes, then we continue” — and be sure to return.
Lesson. Silence without return breaks trust; a pause with return repairs it.
