Need some advice on a girl, its really getting me down!?

Hey! stuff like this happens, Its the growing process, learning how to take knocks and gaining a thick skin for future knocks.. If i were you i would try my best to stop the feelings for her, i know its easier said than done.. But if you really cant stop them feelings then find out how strong her relasionship is with this guy, if its strong then you have to forget her, if she says she's not sure of her feelings for him then thats just as good as saying make your play for her, let her know that you like her a lot and you really enjoy being around her, whatever you say make it have a double meaning so she's unsure whether you want her as a best friend or a girlfriend, that way she will eventually want you as a boyfriend, let it happen all on its own, but dont pressure her, just let it flow and just enjoy her company and the msn chats.. Be kool and chill.. Good luck!
