First, make the return time specific and then keep it. 'Give me some time' is harder to hold than 'I will come find you after dinner.' The precision is not a formality—it is the actual signal that the relationship is still active. Second, after a difficult exchange, spend five minutes writing down the trigger, your first interpretation, what you did, and what actually happened. Over a few weeks that record tends to show that feared outcomes arrive less often than predicted, which makes it easier to stay in a conversation a little longer the next time. Neither practice requires a personality overhaul; both work with the existing preference for concrete evidence over abstract reassurance.
