What should I do? Give her time, forget it,talk to her, tell her how much I like her againg or just be friends?

There's this beautiful girl that I barely knew her knew she existed and both talked once in a while,the thing is we barely started talking a month ago but no joke, since the first phone talk we've had we have laughed ,conversate, shared opinions, talked about future and past, flirted plenty and just laughed for hours overtime we talk each other to sleep. No joke we both agreed we have tons of fun together ,enjoy each ore company, and hanged out recently, she first told me she just wanted to be friends, I said I was ok with that ,later she asked why I really talked to her, I replied that's I started to do it because I just wanted to talk but than started getting to like her for the way she was, my visits to her house after that conversation had been funner, we flirted more and could just tell that we had a little thing for each other, we hooded hands I hugged her she didn't not say anything, I went to watch her at her soccer game called her 2 days later but we know kind of felt more attracted and she invited me over and said she wanted to see me. I visit her we go play soccer just both of us, flirted for a bit went back to her house,holded hands for a bit.. (let me just say lately she has been telling me that I am way different than other guys she knows, she trusts me, she flirts with me plenty, and says she loves my smile,) "thing that not ,many people say" so we walk that night just third nigth going to her house than aging she sees me every moon and wed at soccer practice plus various hours of phone talk and 2 very long visits at her house so we walk to some benches were it's dark we talk for some time and plays around by slapping me slightly I told her to calm down and instead of hitting me that I would prefer a kiss haha she starts to act like a flirt and says that's if I kissed her she would not hit me, I make an attempt but moves, 2 to 3 kin later she kisses me and kissed me plenty for the next. 15 min I asked her why she did this and if she's like that with other guys she replied seriously that if I knew her well I would know that's she is not easily like that with guys and that is rare just like it's rare to meet a boy like me were both 18 .I asked her if she liked me she replied by saying what do you think in a obvious way that she does and kind of agreed we might have something very good going on and high chances of going out in a future. Night was over both very happy putting sweet moods on our myspace. The very next day on the afternoon her mood changes to idk:/ I knew something was going on she said everything was ok until that nigth we text she says that she will not kiss me aging until she gets her feeling straight and does not want me to make a idea or does not want to hurt me because she has gone trough phases that believes she likes someone but does not after looking over. Than we continue talking me saying why the change of heart she continues by saying that does not want a boyfriend and that she prefers to be friends for what we have gone through and maybe were going to fast that by the way I never pushed her and like I said she kissed me first and various times voluntary . She now says that if I feel pissed to stop talking to her because she prefers to stop talking to her than keep on getting hurt but I know that's she's not a tease, or alutty or does this often but aging we had every little thing in common and laugh and talk and flirt for hours (which friends do not do)we could all agree so know what should I do we enjoy being with each other vie fallen for her she kissed me said she wanted to see me but not feels confused over a single day.where do fit or what should I do. And is there still hope.?
