I (22F) believe my ex boyfriend (23M) suffers from BPD or at least something. We broke up in February, but continued to hang out here and there up until last week. Since we broke up, he’s sent me long, harassing emails, despite me telling him to stop many times. He is somehow convinced that i have cheated on him through stringing together random bits irrelevant of information into a detailed story of my disloyalty. He claims that he can’t trust me, because early on into our relationship, i lied about the number of guys i’d gone on hinge dates with before him, and that i was a virgin. I came clean about it around a month later, and he crashed out on me. Ever since, he closely monitored my life360, findmy, we were constantly on ft, even overnight so he could make sure no one was in my room. He would freak out if i didn’t pick up his calls within the first two rings. He extensively went through my phone and laptop multiple times. Mind you, these guys i lied about all happened BEFORE i met him. Anyway, since we’ve broken up, he has reached out to the hinge guys i met before him and tried to come up with a false narrative that i cheated on him with one of them. NOT TRUE. I have never cheated on anyone in my entire life. I’ve been on the receiving end of a cheating partner, so i know what it feels like. Anyway, he can’t seem to let this assumption slide. He is 200% convinced i am an evil, evil person. He has been blackmailing me, and claims that if I just admit my wrongdoing, he will not release my dirt to his Instagram, an extensive list of my potential employers, my friend, aunt, and my family. It’s crazy to me that he wants me to admit to something I’ve never done. I’m pretty much trapped because whether or not I go along with his narrative I’m screwing myself over. He also pretty frequently goes back-and-forth between loving me so much and hating me because I am an evil pathetic person. Any advice on handling this without further provoking him?
