Does she like me? Should I text her first and ask her out again?

My friend invited me to valleyfair with him and his cute friend. So I met them there, after getting to know her my friend lost his phone and left us alone so he could go look for it. After talking a little we kissed, after that she couldn't stay off me. We spent next 7 hours all over eachother, then I drove her home and we made out in my car for almost an hour then befor she left she asked for my phone number. As soon as she was in her house she texted me. I waited till the next day to text her. We texted for a couple hours her messages were full of smiley faces and laughs, then I asked her to a movie. She sayed I'd love to and I can't wait to see you,, but the next day said she couldn't because her grandma was in the hospital. So I told her it was ok and we should do something later. So weve been texting the last couple days off and on. But she randomly stops texting me. I've asked her if she wanted to go to a movie another night and she didn't respond till the next day and just said hey ;) then we would talk for a little then she would just stop for the rest of the day. Then I texted her hey you;) what are you up to? and she just said hi. Not much hub? This bugged me alot. But we talked for a while then she just stoped again. So should I text her and ask her out again or just cut my lose. I really like this girl and want to see her again but I don't know if she likes me or what.
