Hi Madison
My take is it better to talk to her to clarify what has happened. Setting her off is risky. But burying issues is even more problematic in the long run.
I agree with
half-life, I don't think it's ever a good idea to let things fester. Before you speak to her take a look at some of the communication tools on here which might help you.
My pwBPD has just come off two months ST with me also although my situation is slightly different... .after an argument I was ferociously blocked and ignored. It was brutal! After two attempts to reach out I gave up and settled into the silence. He owes me a lot of money and I decided to grow some balls and ask him for it. Surprisingly he responded almost instantly and, even more surprisingly, while I wouldn't say he's been "sweet as pie" he has been totally reasonable, amicable and even courteous about it (!). It has also unsettled me somewhat! Not what you'd expect after everything!
Unpredictable behavior is really confusing isn't it
Yes it is!
I won't be asking my pwBPD about his ST - I can't handle a relationship where he behaves likes this so his reasons really make no difference.
