She says she's not ready but I think she likes me. Please help?

Ok so two days ago me and my friends were hanging out for about 5 hours and I was extremely hyper that day so I started acting out and the girls like to her friends " Oh he must be bagging all the girls" I've known this girl for months and this is the first time I heard her say that so I thought that was my cue to ask her out. So we get on the train and everybody leaves except for me and my friend and her. So she gets off two stops before me and she knows that so I tell her that I have business to take care of she's like "ok" then my friend asks me secritively "why are you getting off at th same bus stop" then I'm like "I'm going to ask her out when we get off" then the girls like "what happened?" and I'm like "don't worry about it" then she's like "c'mon tell me" then I'm like "you will find out son enough" then she's like "what do you mean" then her friends start talking to her so that diverts her attention from me so then our stop comes up and me my friend and her get off and as we are walking down the stairs she's like "now tell me" then I'm like "nah I can't" then she says "c'mon I'm a big girl I could understand" then I'm like "nah I'm too scared to tell you" then she's like "c'mon please tell me" then my friend says "c'mon tell her" then she's like "what, you wanna go out with me?" with a big smile then I'm like "ya" then she's like " I'm not ready for a relationship right now I just wanna chill" then I'm like "please" in a humorous kinda way then she's like " no " with a smile then im like " ah bummer" I walked her to her house and she says " why didn't you ask me tomorrow" then I'm like "because your too special I thought if I waited too long someone else might have asked you" then she's like "aww" and stomped her feet maybe because she wants to go out with me but she's insecure. Then she was also like, " I feel bad now you have to walk all the way to your house. " then I said " I would walk the ends of the earth for you" then she stomped her feet again and said "aww" later she's like "your a sweet guy" and another time she says " a lot of people ask me out and I don't really know why" so do you guys think she wants to go out with me because I really really really like her but I think she's insecure also she says that she has to go to college soon and she's gonna have to apply herself considering she's a grade A student. Thanx a lot for your guys help.
