Last year I was going out with a girl who was in love with me at first, but then I started singing in a band which meant every day after school would be practice, and even though I;d invite her to come hang out with us she always said no and would always hang out with my best friend. Eventually it got to the point where she started falling for him and I told him to cut the shit but he wouldn't and I almost beatthe shit out of him because of it. Anyhoo, she broke what we had to go for him and he broke her heart and she wished she could come back to me but I was a stubborn asshole who wouldn't even acknowledge her existence anymore. Earlier in the year she came back to me and she was all I ever wanted, but before we could start anything new she left me AGAIN for another friend of mine. So all I can say to you dude is just find another or beat the shit out of this guy, if you give it time you'll eventually get over her, it hurts but it'll be worth it when you find someone better and closer to you.
