High fit

Sync is about alignment between what you feel, say, and do. In the anxious-avoidant cycle Alex Cooper describes, both partners are wildly out of sync: the anxious person says 'I just want to talk' but the behavior reads as attack; the avoidant says nothing and disappears. The repair advice — state when you need space, ask directly for closeness — is essentially instructions for getting Sync back online so that what each person actually needs matches what they're communicating.
