Search Results: asking a girl to prom

Ok I just started talking to this girl a couple weeks ago when we started talking on face book she asked for my number so we can text. Then she started texting me a lot then she would text me asking if I wanna talk on the phone and we talked on the phone every night for a couple of days then I asked her to prom she said yes. Then she would text me morning for the past few days then she stopped then I wait for her in the morning and I would walk her to class in the morning and sometimes hug her before she gets on the bus I'm not nervous around her at all I can talk to her fine. Then one day we went to take SAT's and she has guy befriend from another school that week took the SAT's at yes I was jealous but I just ignore it cause she didn't pay any attention to me but understanding she knew him longer so I brushed it off and skipping ahead later that day she called me sayin remember when I said I had another best friend from a different school and stuff so I'm guessing her guy friend said something cause I didn't bring it up and she asked if I was cool with I said yea but I really wasn't . Then she said can she ask me a question if I like her more than friends and I said yea then she said omg why didn't you say anything I don't know what she ment by that did she like me? And since then things haven't changed we still text, talk on the phone sometimes, I still walk her to class, and were still going to prom

my main question is I have a pretty good feeling she likes me and how would I ask her to be my girlfriend I never asked a girl before I'm a senior and she's a jr
