My bestfriend and this guy dated in August ’15 and stopped dating after a couple of days. Around Christmas we started talking and turns out we have a lot in common. I told him that I didn’t feel the same way that first week we spoke. As time progressed I started to really like him. At one point he came to my house. We were talking for a really long time. In April I went to a hospital for a suicide attempt. After I got out he went to prom with another girl, asked a close friend for nudes, and just recently began talking to my best friend. I can’t get over him and it’s making me depressed. What should I do ??
