I'm sorry this has happened again. We're here to help you find some solutions and to support you. I'd like to encourage you to post in Newcomers....you will get more and more varied responses.
Have you read Divorce Remedy? You seem to know about the '180'.
First, stop having relationship talks...especially 'status' type talks. They are taking you on a downward spiral, and it just gives her more chances to speak about finances. If you find yourself in a talk anyway....dig deeper about findin out why she thinks you're manipulative and controlling...but just listen...don't argue or give any defense. Just try to understand.
The 180s you made before....Did you continue those? What were they?
