I was friends with a guy for a few years. We met at a place where I used to work and formed a pretty close bond, even hanging out a lot well after we both quit working there. We had a lot of fun over the years and confided a fair bit in each other but there were some red flags surrounding the guy that popped up a few times that kinda escalated to the point where I felt I just needed to cut him off for my own good. For one, he seemed to get jealous every time I said I was busy hanging with some of my other friends or that I had plans with family, etc. Secondly, he often pulled a lot of sleazy shit - shop lifting, drug dealing, emotional manipulation, constantly fucking around on his woman then blaming her and pulling the victim card (believe me the shit he constantly drug her through is enough for a whole nother story), the list goes on. He picked up a bit more of a drug/drinking problem and constantly wanted me to go "get fucked up" with him almost all the time which I was starting to get real bored with, not to mention it was kinda destroying my health, so I would start declining his invites more and more. As his drug problem seemed to escalate, he started acting more and more strung out and paranoid (go figure). The last year I had contact with him he was constantly pushing for me to come visit him and stay the weekend at his place... like a lot. He was overly insistent that I stay the weekend at his place. Something just seemed weird and off about it to me so I just kept shutting him down. Not too long after, I started ghosting him altogether. I moved away not too long ago and he's tried reaching out on various platforms saying he's "changed" and sobered up but I've never responded. I feel kinda cold for it and frankly a little chicken-shit too but I firmly believe I can't trust the guy. Idk, sometimes I still feel guilty and that maybe I was being too paranoid myself.
