Please Answer? Help Me Out..?

since i met this girl last september 10' (its not june 11') we've been on and off ALOT. we've gone out AND broken up like 20 times. im REALLY attracted to her and her personality, and whereas im not the most attractive guy, she says she fell in love with my baby blue eyes. Inbetween us breaking up and getting back together, my best friend (who is the one all the girls have crushes on) has been trying to steal her, and she likes him alot aswell, anyway, we broke up a few weeks ago and i was really sad because i really dont know why i cant just get over her. She told me she broke up with me because it was 'sudden' and 'weird' but she told my friend its because it felt like we were just friends (although she said it was to early to kiss, which confused me, as one day she wanted to kiss me and didnt tell me then the next she thought it was to early.) Now that we've broke up, my best friend asked her out and she said yes .. which has made me feel even worse, because a) he is supposed to be my best friend and b) all the fun we had in our relationship she is now showing to him. and i cant stand it! They've been going out since we broke up and they havnt even hugged yet! (me and her hugged on our first day!) and then she says she dumped me cos it felt like we were inly friends! i still REALLY like her, and i dont want to lose contact and make her miss me because she will think i hate her and then she wont ever talk to me again. i dont want to make her jealous because i beileve thats not fair on the other girl. i just dont know what to do! im heartbroken, please help :(
