Breakup because of BPD.

Its been a few weeks since we broke up, and I now suspect he broke up with me because of my BPD. It's hitting me like a bus that I'm a horrible person because of something I can't control. I've felt extremely depressed and empty without him. I feel like just offing myself for good to keep me from abusing anyone else. I don't want to be evil. Sorry if this makes no sense.
