How can I forget a past girlfriend and how and I get enough cofidence to talk to

[JIF4994]

new girls? I'm a big guy and I've had girlfriends and I broke up with the last one in July. Lately I've been thinking alot about her and I don't know why and I want to forget her completely. I hear from people that finding someone new will make you forget but I want to forget without finding someone new. I also Can't find enough confidence to talk to the really good looking girls because I'm a big guy and that's the only thing that I'm afraid of them thinking is that since I'm a big guy, I'm not worth their time. If you have suggestions for either one, leave a comment or whatever it's called
