I like writing a letter of "restorative justice." Restorative justice says...this is what you did, this is how it made me feel. A way of taking your power back (that was stolen as a child). The letter is for YOU....she can't interrupt, etc. and you can get to say what you need to. Rarely will an abuser admit to what they did. They are narcissstic and not capable of feeling anyone else's feelings.

What do you know about her childhood....she probably was abused and repeated that cycle (of course that doesn't absolve her), but may explain her behavior.
