Looking back at it, I just want her to admit she was wrong and a single apology. Only closure I need to get past the hate.
I have a friend who went through a divorce and he more or less told the couples counselor the same thing. The guy said to him "has she ever done that in the entire time you've known her?" The answer being no, he realized it would never happen and let it go. Obviously I don't know your ex, but you might want to think about whether you need to let that go for your own sake.
