This could be her just having a good time, but I've always believed that when people do something like this, they know the consequences of their actions and either they chose to do it anyway or they chose not to. She knew the whole time (unless she has a mental brain disfunction and cant keep up with what she does) that she wasnt calling you.

If I were you I would give her a taste of her own medicine. How many days was it that you didnt talk to her? three?
When she calls dont answer for three days. People will disagree with me saying its playing a game, but when it comes to relationships they are games, and either you learn to play or you lose. Your choice...
