Boo, I feel for you. Stay with your mom and stay away from your qualifier. You'll think more clearly once you're away for a bit.
Had a similar thing happen to myself. Xagf was texting and calling me saying she was going to tell the police I abused her, when I never did. I went to the police to make a report and advise them that xagf may make a false report. Said I did not want her arrested, that it was just a FYI. Cops arrested her any way. And they got me a restraining order. I feel really bad that x got arrested and hope she gets off easy (don't know why I feel that way, she was always very abusive). The restraining order is a godsend. I feel much more peaceful without her causing chaos and panic in my life.
