Does she want me?

Right heres the story. I really really like this girl and i cant tell if she likes me. We are both 16 and attend the same college. She knows i like her and i dont know if she likes me back. She would often do little things like call me gay as a joke ebven though she knows i like her, last friday she would throw footballs and little apples at me to try and get my attention. She told her and my best friend how she wants me to talk to her, why doesnt she talk to me? she also told them how she wants to get to know me better but doesnt approach me very often apart from the throwing and the name calling. What do you guys think because i am holding a party tormorrow and said she would be happy to come.
