It's a shame, but she's actually acting toward you the way abusers do toward their victims (accusing the victim of harassing them). As upset as you are with her, do your best to summon up some compassion. Abuse can get someone ALL twisted around--we even do presentations on appropriate handling of criminal cases where the abuser has coerced the victim into committing serious criminal acts. They don't get a "pass," but we do encourage prosecutors to factor that into the appropriate disposition of their cases.
