If she isn't going to give you the time of day, then she obviously isn't worth your time either. Move on, and find someone else. There's plenty of people out there, you're going to find someone eventually.
Ismail is right dont over analyze!! Be a man and be real tell her how you feel. Be confident if she dont like you back just say oh well her loss. You'll find somebody if I can U can. I am a b*tch tp put up with. Have a little FAITH.
