I'm starting to think I have a trauma.
Around two years ago I had a "friend" in college who would play online vidya with me. We spent many nights griding guns on Borderlands 2. Really fun times.
Then he asked me out one day. This is a guy I barely saw on campus and with whom I only talked with through in-game chats because neither of us had mics. I knew nothing about him other than he was fun to play games with, so I turned him down.
He then goes and says "But we've been playing games almost every day for two months, how are you not interested in me?". Needless to say I got really fucking mad at that and told him to just leave me alone, but of course he didn't.
For almost 6 months he would try to guilt trip me into becoming his girlfriend or else he would kill himself/quit college(he constantly alternated between these two options). In the end I was the one who quit school, and just because of this guy.
I've blocked him in every possible social network and even changed my phone number, since he managed to learn it from someone back at our college. And that's where my hypothetical trauma comes. I've completely stopped socializing, even with girls (though in high school a classmate who I considered a best friend came out to me as a lesbian AND asked me if I wanted to be her gf on the same evening. We never really got along again). Every guy I meet on the internet thinks I'm a guy too as I've taken to pretending to be a man online. So far it's really helped as I've never had to deal with clingy types like that guy from college again.
Is this some legit form of trauma? Being overwhemingly scared that people will always want more than you're willing to give? I honestly can't see myself making IRL friends again.
