Also...being deliberate about whether or not the question or accusation even needs an answer.
Especially "accusations". pwBPD seem to love to "put people on the witness stand".
I used to jump up on the witness stand at every opportunity and would usually "prove" myself to be virtuous and that the accusation wasn't true. To me (at the time)...that sounded like good stuff for the relationship. Yet my relationship got worse and worse.
Eventually I stopped accepting the offer to get on the witness stand. Sure, my pwBPD pitched a fit...but things slowly got better.
What if, instead of getting on the witness stand we found something valid to validate? Hmmm?
