Ok...whats your question? why do girls play games? Because guys like you let them !!!! Only people can get away with what you allow them to get away with....obviously you never confronted her on the issues you mentioned above therefore she kept doing them.....and why do you want to be cool with someone that does that to you? Leaving you to go with someone who is ill, then talks bad about you, uses you and hates you for reasons you never mentioned other than you moved on??? this girl is coco loco.....pick yourself up and reevaluate this situation...your wasting your time...but you need to figure that out and sounds like that will take time to do..........there really is no good answer for you.....she's a bad cookie !!!
