I'm following this thread and pondering the connection to my M.
I think my M could have been saved with MC and IC. W refused to go. W refused to go to an IC her whole life and deal with her issues.
W refused to admit any fault, to make any changes in better communication. It drove me to try to force her to see her faults. Which was then my fault to try to force it. If she at any time showed any interest or ability for healthy communication, I backed off. But it was seldom and never lasted more than a few hours. I now believe she never did agree with anything, she just said she did. She thought she could do anything she wanted, we didn't need to compromise. Throw in an ugly childhood/past with abusive/abandoning parents on her side, no amount of laws would have fixed it. After BD she finally seeks out an IC.. a one sided ignorant IC (I believe anyway), feeding her victim mentality, it gets worse again.
