LOVE ISSUES! HELPP GIRLS OR GUYS!!!?

theres this guy and me and him use to be really close..but as firends..i develped hard feelings for him but didnt tell him about it. so one day i made a move on him and kissed him in his car when we were alone. he kissed me back. but after that we kinda grow apart. but my sister's bf whose his best best friend told me he has feelings for me and his not the type to show it. so we both felt that way. after a couple of months we were with different people. but we were still freinds. So i move to FL. and my sisters bf tells me hes been talking about me alot like the time i kissed him and stuff. he told him he wanted to be with me. HE TOLD HIM THIS AFTER I MOVED!! then my sister got prego and her bf moved in with us. After that me and that guy have been talking on email, Myspace everyday! for about a month and a half. its hurting me deep because hes telling me hes proud of me and i was the only girl really for him. but he gets alot of girls. this guy is not ugly. i think about him everyday and now he wants to visit us but i doubt it. hes that type of person. lol but should i stop writing to him and get over the fact that i cant be with him or should i just face the fact that i might possibly love this guy and continue. Oh im 16 and he 18 if that helps. Please help! i dont think i can have anymore heartache
