I (30/f) have BPD. And I currently don't have access to my therapist until my new health insurance starts in January. I do suspect my bpd diagnosis might be the reason my ex bf  (31/m) broke up with me when I was diagnosed this year, around April. He broke up with me towards the end of July. He claimed that he just mentally couldn't be in a relationship due to his depression issues, but apparently that depression healed up pretty fast because he is now in a new relationship and flaunting it all over social media. We were on good terms, but I had to block him after I saw the new pics he posted with his new gf. I don't really know why I'm still feeling intense jealousy, rage, just still obsessing over him even tho I don't want him back...I've dated (and currently dating) multiple guys, it's not like I don't have options but it's just really messing with my feelings seeing him with another woman. 

I guess I just want to find out how he healed so fast? A month ago he was still claiming that he still cares about me alot etc etc, and now he's posting about starting new holiday traditions with this new chick. I already hate her and I don't even know this chick, and I'm not exactly sure if I blocked him due to his new relationship status or the fact that he downgraded?? 

Anyways, this is still fresh so I just need help thinking rationally, because I really can't right now. I can't stop obsessing over this new chick, I don't understand what he sees in her that he didn't see in me. 

Can't really talk to my friends because they don't understand bpd and how intense it can be, and I can't talk to a therapist until sometime in January when my insurance kicks in...
