There is this girl. I kind of like her but im not sure if she likes me as much and i dont know what to think.?

I have a date with my friend who is yes a girl to homecoming and im not sure like what to exactly feel about it or her. i kind of like her allot and she acts like she likes me too. (we were smokin and she kissed me) and we've kissed before. We hold hands in the hall and i kissed her in school the other day. Lately shes seemed more distant though and when i asked her out a while ago she denied me! -ouch- yet she still wants to go to homecoming with me! im getting sick and tired of all that's going on and homecoming is this Saturday. What should i do?
