I love that she changed her mind about your ex!!!

The whole 'nice' thing really bothers me. I am not sure if your mother is like this, but mine will do something 'nice,' but then complain about what a sacrifice she is making - when she could have just said no in the first place. Or she will do something nice that is really just a way to exert control.

So I think it is okay to be done with nice and sacrifice. She is making a choice. If she doesn't want to be nice, she can stop. If she's being nice just so you will do what she wants, that isn't actually nice at all, you know? They are very tricky!
