*10PTS BEST ANSWER* Is this girl prude or she doesnt like me? Give me ur opinion?

I knew her my whole life she is 15 but cant date, we would flirt with each other for an example one day i was touching her and she would stretch and touch my hair but i would be the one to touch her and etc. One day she ran into a dark room i ran in there too we both stared at each other than her eyes became wide and she covered her mouth with her hand ( Was she nervous/scared ) I would have kissed her if she never covered her mouth. We will talk and have great conversations than when im about to leave she says wait because we will talk more but the other thing is that if i sit/lay near her and if i touch her she would move away. She tries to avoid me i think im just confused right now what is going on. She called me ugly but i know girls find me attractive and this one girl called me ugly once but than later she told me she thought i was hot.She can be a little mean to me sometimes but if i ask her to do something for me she wont deny me.
