The sort of repayment that feels like a swift kick in the nuts. Did you confront her about it? Demand monetary compensation for time wasted?

I suppose it makes sense, though. Abusers spend years breaking down the self-esteem of their intended victim. It isn't like some good samaritan is going to undo all of that mind****ery in a single afternoon over tea. I'm not even sure it's possible to restore someone's confidence if that person is living under the same roof as their abuser and being subjected to gaslighting for hours every day.
