I honestly don't know what I should do anymore?

Try to get her back. Say I'm sorry I rejected you but I changed my mind. Nothings wrong with being lesbian or bi, your just a normal person but with different tastes, trust me I would know, I have a lot of lesbian friends and bi friends (and gay ones) but they dont crush on me (except for 2) and I just accept them for who they are not for what they do =) Im straight BTW -_- ___________
