So I'm pretty late to being an adult. Had my first gf at 26, but I learned the true nature of women before that. So I was really careful over this first gf. But of course, months later, I find out she's secretly hanging out with her FWB. It's been a year since that, and I still heavily resent her for it. I'm breaking up with her today because I'm sick of her bpd neediness.... But I need help. How do I move on from constantly thinking about the past? I can't shake this feeling of feeling like a bitch over being with someone for 15 months even after they did something like that. How do I do it?
