Let me start and preface this with noting that I understand this is Reddit and not a board of licensed psychologists, but I figured a lot of you know a thing or two and might be able to lend me some helpful advice. My( 18f) bf,(20m) , has some weird behavior that I’ve not been able to find resources on and I’m really concerned as to where it’s stemming from and what exactly is causing it. He is insanely paranoid, and not in a cheating way (he’s never accused me of cheating in the 3 years we’ve been together), but in a “I’m always afraid you’re hurt or will get hurt” kind of way. Throughout my senior year, he would continuously show up at my house and bang on my window in the dead of the night after convincing himself im not okay and basically inducing a panic attack. There were times I’d even have him on call in the room over while I went to go chill and watch a movie with my parents in the living room and he would still freak and come up with some irrational idea that I’m hurt or not okay. It’s almost as if he lives in a reality where he thinks everyone is out to get me and he must be there to protect me or something. I live in the suburbs and have literally never had a problem or run in with crime, yet he acts as if I encounter it daily and is always telling me to be safe 24/7 , he’ll even say it if I’m doing something as simple as leaving my room to going to the bathroom. He knows likes us to FaceTime at bedtime so he can see everything going on just in case something happens. He was never really like this in the beginning of our relationship, but then again also hid that he was mildly suicidal and had a lot of trauma from childhood abuse. I’m not sure why he’s like this and why he’s only paranoid about me, and why if it’s possibly related to mental illness that he didn’t show any of those paranoia or obsessive thoughts within the first year and half of dating? He also feels like he has no identity outside of me and I’m his only reason for living (although the has friends and the alike) and almost like he needs me to live as someone would need oxygen to survive, which definitely sounds more like unhealthy attachment or obsession. I’ve never heard of someone acting this way in a relationship and when I try and find resources on this sort of paranoia, I’m only met with the average cheating partner paranoia.
