Troubles

I like a girl who previously liked me, and had asked me if Ituliked her, I was confussed and turned her down. Now, ever since then I have been trying to win her back, but to no avail. I have liked her for 6 months now and I am currently in our summer holidays, so Im not going to be able to see her for 6 weeks. I dont think she even has intrest in me as a person anymore, so Im feeling pretty down. I have untill next year before we leave for Colledge and would really like to go with her to a dance, but she could careless for me. Now I am sitting at home, alone, thinking for her. :( HELP!!
