Self-respect is staying recognizable to yourself while emotions try bargaining.

Strong feeling makes offers. It suggests that just this once the standard does not apply, that the circumstances are exceptional, that you can go back to being yourself tomorrow. The bargaining is persuasive because it comes from inside and uses your own voice. Self-respect is what lets you stay someone you recognise while that negotiation is running, without having to win an argument against your own emotions.

Decide the important things in advance, when nothing is pulling at you, so the decision does not have to be made mid feeling. When the bargaining starts, name it as bargaining rather than as new information. Then wait, because most of these offers expire on their own within a day.
