I've re-read the last resort technique in the DR book. And it feels less extreme than I remember.

I have read people on this board saying things like isolating your finances, sleeping in seperate rooms, not engaging in conversation. Per my situation above, I feel I need to change the dynamic and somehow confront this potential deal breaker (of OM working at the same place as my W). One idea I had was to have a talk - with me acknowledging how she feels about me and our broken marriage, but that I could no longer accept being lied to.

I'm really struggling with how to deal with this or address it head on. Help!
