Well OK so we will start by saying I'm 17 turning 18 in a couple weeks . I met a girl named Sarah last year in December at school . We became good friends and I like her. A couple weeks after this I met my girlfriend Larissa . Since last feb 2010 we've been dating. I've always had feelings for sarah . And in the summer when I had problems with my relationship we would talk on the phone for 3 hours at a time. Sarah recently got a boyfriend 3 months ago . I want to tell her but I don't know :( what do I do ?
