Welcome
Sandrita!
Thank you for sharing a bit of your story and what brought you here. I'm really glad you found us.
Am I correct in assuming you think your SO has BPD traits? It's beyond tough to survive in a relationship where someone has BPD. It's natural to be struggling after a breakup.
A pwBPD sees the world very black and white quite often. If my uBPDm decided she didn't like someone or decided she was hurt by them, she would cut them off forever, and paint them black to anyone who would listen. While it's so sad, I'm not surprised that your SO is telling his family and friends that you're the bad one. It's their way of 'self soothing,' odd as that may seem. It allows them to feel better about themselves even if it's not at all true what they're saying.
Do you feel as if that's an acurate description of what you're going through?
