I totally agree with Heartless. Every girl goes through a " bad boy" stage. Their " I don't take poo from anyone" attitude is really sexy. And yeah; the chase is fun. Anyone, a girl or a guy, can end up liking someone more because that person wants nothing to do with you. Its crappy, but thats the truth of it. No, not all girls are like that, but a lot lot lot are. It's conquering that tough guy; there's no challenge in a guy you know wants to be with you.
But, yeah. Forget her. she'll eventually realize the mistake she made. And then you can just laugh in her face.
And theres a term for those girls that are all about a guys clothes/car/house/money: golddigger.
