What does a girl gain by continuing to treat me like shit after a breakup?

Like she’s rude and it’s almost like a complete personality shift to the girl I was initially interested in. Also the arguments caused the breakup and many of the arguments were her throwing temper tantrums cause she couldn’t get her way and when she couldn’t get her way she would call who would listen to her and make me the bad guy. When something happens to her everyone has to drop what they are doing and Cater to her. But when I have something going on she couldn’t have cared less.
