Asked a girl out... but she said possibly?

I know this isn't a good sign but I don't know if I should ask her out again... I mean I didn't get a straight answer. I feel that she likes me because of the way she acts different around me and other people. But what do you guys think? Should I ask her out again or stop because she isn't interested?

Thanks!
