 

I have diagnosed BPD traits so this situation has triggered a lot of the traits I'm working on managing in therapy.

A few days before I admitted my feelings to my boyfriend, he drunkenly said he still loved his ex-girlfriend who he broke up with last February.

Several days after we started initially dating, he drunkenly messaged her ex-boyfriend as well to ridicule him for also having been cheated on by her.

He has since profusely apologized for both incidents, and explained that he was "confusing missing being with someone with missing her specifically." But when he told me he thought he still loved her, it was very specific to her. Concerning him messaging the ex-boyfriend, he admitted he was petty and felt satisfied that he was also cheated on by her.

I am struggling to believe his explanations and his apologies. He has treated me well since, and has gotten emotional during our arguments where I feel insecure because he feels so frustrated that I don't believe or trust him.

However, I have been used as a 'rebound' in the past after ignoring red flags and I don't know if I'd be doing the same by continuing to pursue this relationship. We started dating in late December so it's been around two months.

Should I believe him? What should I do?

TLDR: Drunk boyfriend said he still loved his ex right before we started dating. Then drunkenly messaged her ex-boyfriend while we were dating. Claims he is over her and that he is just a bad drunk, has apologized profusely but I'm struggling to move past it. Should I believe him or should I move on?
