So, one more question and it's one that has tormented me for months: How do I do this without being the one to leave? Break out the 2x4 if needed, but I'm serious. I have told her to leave, I agree it's over, all of that. She won't go. I told her to go back to sleeping on the couch. I no longer fawn over her, I listen when and if she talks to me and I validate my a@@ off. Do I file myself?
Do not file unless you want to divorce her. Don't do it as a tactic.
Think about what she needs to feel safe to leave...
