I want her to see and feel the guilt of the destruction she's causing. I so hate her right now.
Boy, do I understand that feeling.
You've got to realize though that it's not productive.
She's going to do what she's going to do. Wanting to see her guilt keeps you focused on her, not you.
Your job regarding your STBXW right now is to keep things as positive as possible for the sake of your daughter. Dwelling on your negative feelings toward her will shut you down. Pushing guilt on her will cause her to shut down. It ain't worth it.
Especially now, that you're trying to get her to mediate with you. She needs to see you as someone to work with.
Not saying this as a master of any of it, I'm living the same dynamic to a degree. But figuring out what's worth it and what's not - with respect to what I REALLY want right now - which is for things to be easier for me and the boys, vs. being invested in what the future former Mrs. feels and does.
