I lost my true self and became a man who strived to keep her happy. Jumping through hoops became a part of life.
Well said, tnbh. For many of us, that describes the dynamic in a marriage to a pwBPD. I'm sorry to hear what you are going through, all of which is quite familiar, and admire your resolve. Be grateful that your marriage was short (6 months) whereas many of us suffered much longer in hellish marriages (16 years for me). You seem to be on the right path, though I know it's a difficult journey.
