Head games yah my favorite subject... Depending on where you are in life you can either A take Billys advice and play the game, be friendly, dont be interested in here, if she has any friends ask them out on dates.... start getting chummy with all of her freinds so she cant avoid u at all. In a rare case she might even start to get intersted again, then you crush that bitches heart like a egg under your foot. Make her pay dearly for being imature and not giving you your god gievn right to an explanation. Tear her down to nothing, and i promise u this u will ba labled an asshole for doing so, but you will have struck a blow deep into her soul and i promise that she will never do what she did to you to anyone again in her life.

Or B
Ignore to bitch, move on and be glad your not involved with a selfish peice of shit.
