Should I keep ignoring her?

This chick sounds like she knows how to make the boys chase, so here's the thing, she may get lots of guys hitting on her all the time, so if you distance yourself too much for too long, she'll lose interest and move on. Girls are like that, especially hot girls, you've got her chasing a little simply because you're playing her at her own game and she hasn't figured it out yet. The trick here is to give her enough attention to keep her interested, but not enough to let her think she can toy with you. Play this game for a week or so, but again, the time will come when you might need to take it to the next level (maybe ask her out), or she'll become bored with the game and move on (remember; just because you're gaming her, doesn't mean others aren't, she may have loads of options so if you mess around too long, she'll turn her interest elsewhere). Good luck, and most of all; have fun :D
