Title says it all. One of the dumbest things I've done in recent memory. But her body was exactly my type and she came on like gangbusters. I typically have no problem getting over a chick after a few months but seeing her everyday at work is really dragging me down. It's a good job so I'm just going to muscle through it.

Here's my question: When I dumped her she started getting real close with this kid we work with. He's 5 years younger than her, lives at home with his parents, has acne, etc. I've seen him do some of the most beta crap with her, i.e. he helped her move to her new place. Defends her around the office saying sh*t like "She's my friend" blah blah blah.

But I can't help but wonder if she threw him some p*ssy, too. That part REALLY f*cks with me head. I've seen guys she's dated in the past and a-lot of them seem chumpish. It's really crazy because she is very attractive and sexual but has incredibly low self esteem. The sex with her was wild. But I can't help but still wonder, could she have banged this extreme beta to try and make me jealous? Do BPD women sleep with guys that are complete orbiters/afcs or do they just use them for things? What's your experience with this been like?
