I met this guy in June and I fell in love with him by August. I thought I knew everything about him, then he started cheating on me, and talking about sex. Every single conversation we had was some how about sex. He cheated on me with me best friend once, and I gave him a second chance. I gave him so many chances. This last time we dated from October 23rd til Yesterday, we broke up because I was cutting myself. He told me that he didn’t care that if I died, and I kind of feel hurt by this. He was the first and only guy I’ve ever fallen in love with and my heart is crushed. What do I do?
