They all KNOW this is classic BPD manipulation.
Hi crystal, Sorry to hear what you are going through. Unfortunately, it is all too familiar. My BPDxW threatened suicide 10-15 times over the last five years of our marriage. Yes, it is the ultimate example of BPD manipulation and it's natural to feel worried and/or guilty about the "what if" scenarios. Even though I knew my BPDx was crying wolf, there was still that nagging feeling in the back of my mind that maybe she was serious on that occasion, which was incredibly stressful. I don't have any particular answer, either, except to suggest that suicide threats are to be expected from a pwBPD. I am even a little anxious thinking about your situation because it could easily be me in your shoes.
Lucky Him
