Girls: I need advice SO BAD about what to do?

I have known this girl for over two years now. We used to kinda date for like two months. It was more like a fling. She ended it because I screwed up with prom and was like a p*#@&. Now we are sort of friends. We had been texting each other at the beginning of summer and things went well but then I ran into some trouble. I asked her if she wanted to watch the NBA Finals with me. She responded Yeah, but she was thinking about going to her friends condo for a viewing party. She said I should come with or we would just watch it. I said either one is fine by me. Then she asked me Honestly, Where do I see this going? I responded what does she mean. She said what are we doing? I then responded I enjoy hanging out together. Then she did not respond. We never watched the game together and the next day after the game I texted her to see if we were ok. I got a short response we're fine. Then the next month and a half had been small talk. I texted her a week ago and just made small talk it went well it was light and didnt seem to have any problems. Then a week and a half ago I texted her and she was distant. I am so confused. We have different friends and the only time I would see her is hanging out together. I like her and I wish I could of done things right the first time. I finished my second year of college and so did she. We both went to the same high school in Illinois but we went to different colleges. I was thinking about giving it a week and a half off and then try talking to her again. I like her. What should I do? Thanks.
