Relationship: What is going on?

I need some help with a relationship issue. My main problem is that I can't figure out what a girl is thinking or what she wants. Here is the situation...
This girl and I had been exchanging looks for several weeks. I asked her to prom which she vaguely accepted because she wasn't going with her boyfriend. Concerning her boyfriend, she has told me that they almost broke up once or twice because she was no longer interested in him and that she had cheated on him twice. Later she said that she was going to go to dinner with her friends and that she would meet me there and "dance with everyone." I took this as she wasn't actually interested but when I asked her about it she said that I was the one that didn't seem interested. She knows how I feel about her and when I asked her about how she felt about me, she said that she will tell me in person "so there is no confusion." Also she said that I should know. She implied that she might go with just me when she "gets to know" me better.
My problem is that I know she feels positively towards me but I don't know to what extent. Also, the boyfriend problem has been plaging me, is she going to break up with him or am I a possible person for her to cheat on him with? Overall, WHAT IS GOING ON?!

one thing is certain, she is a cheater. and my philosophy is - once a cheater, always a cheater. and she sounds very insensitive to me too. forget her, she is just fucking with you. you may be able to hook up with her for a while, things may even be pretty good. but if she was really serious, and actually in to you... well she would be behaving much differently.

I don't think that she is insensitive at all. Last night she was broken up over not going to a friend's birthday party and was actually crying. Your response seems a little bit off base except for the last part which is kinda what I was thinking.

Evan--

Wyote I think hit the nail on the head about cheating. She cheated on him, so what the hell is the difference? If she cheated on him she'll do it to you too. UNLESS by some miraculous act of God, she gets some sense knocked into her. But I've found that is rare. How old is she? I think what I've figured out, is that the kind of guys, that are willing to commit themselves to a relationship (at our age), seem to fall harder for the girl then the girl does for the guy. I've been experiencing this first hand the past month, and I've been learning a lot. I'd sit, and have a serious discussion with her. Talk about trust issues, how can you trust her if shes already been unfaithful to someone else? Talk about what she wants, tell her what you want. Good luck man, girls are freakin impossible. lol.

haha yeah same here.. i try to establish the trust by always keeping my promises and making a point of how important it is to keep your promises..

you're only as good as your word.. if you promise to be with one person and one person only then DAMN IT you better do it..

ok...it seems to me she is playing with you....im sorry....but, i dont think she's interested in haveing you as her boyfriend,i hate to addmit it but i have lead guys on in a round about way...maybe she likes getiing attention from you,maybe she likes you as a friend,maybe she's keeping her options open...maybe she's just looking for someone new to cheat on her boyfriend with......either way,i think you should look for a different love interest....sorry

joel.......hey,boys are no picnic either

i think i know what your doing maybe you don't really like this girl you just think you do . the attention she is giving you makes you feel wanted so you amp yourself up to like her. i should talk i do thet alot

I would stay away from that one. If she cheated on him, she'd cheat on you. She could be the type that just plays with everyone's feelings.
