I feel you on this bro. I was with someone for 2yrs to the day, she started talking to this guy who was a complete loser, I mean exact opposite from me and it made me feel like crap because I was thinking "this is the type of person she is going to after me?" I started doubting who I was.. After all, this guy wasn't doing anything with his life, was an asshole, and ended up getting fired from their job due to stealing out of the register.. whereas I was going to school, working, and plan to attend law school, I know I will do good in life if I don't give up. Anyhow, didn't speak to her for a year and a half, but we finally did and talked about everything, but as friends. Apparently, she didn't get with that guy because she liked him, but rather that she used him as a means for her and I to break up because we needed to. Which I agreed we needed to break up. Anyhow, I will let you know this, since I went through the same thing as you about other girls, it gets better, just give it time. Try to spend time learning about yourself, I know I did and definitely like myself better now than before. Hope things get only better for you.
