Don't sweat it so much dude. Chances were just as good that dancin with another chic would drive her nuts and make her want you more. Lets her know you aren't easy pickings and she'll have to hunt you.
Of course it obviously didn't go that way, so maybe she's just a bitch or maybe she wasn't really that into you in the first place and you are overanalyzing.
Then again what the hell do I know, I am a whipped married guy and haven't been to a club in years
