Replying to What does a kiss mean?

I have had a start to soemthing with this chick. We drank together and made out a few times, then I took her out on a date that seemed to go real well. At the end of the date, she said "you know, if you would have asked me over to your dorm, I would have came." It was too late at that point. Anyway, she has seemed a little dissmissive about hanging out with me since then. I have seen her 3 times on accident though. one of which she kissed me out of the blue. Another of which, she was really drunk and didnt seem to pay much attention to me. And the last of which, I kissed her, she kissed me back and giggled.

The question is, judging by that, is there even a chance that she DOESNT like me anymore? We have had plans for a while to hang out with a bunch of people tonight and when I kissed her and she kissed me back, I would think that if she wanted to, she could have pretty easly pulled back and said "I think we should just be friends." But instead she kissed me back and giggled. The only reason that I am scetched about this really is that I suggested another date on thursday (tomorrow) and she said "I have to check my scedule" which seems really flakey to me.
