I agree 3 months ago I would have done anything to save my marriage.
Knowing what I now know, why on earth should any sane self-respecting person put up with this/his/her cr@p?
At some point we make our own journey out of our own issues with co- dependency Or whatever and see reality for the first time.
We did not break them it is not our job to fix them.
This is my/your life and I/we am/are responsible for my/our own happiness. I do not need a personality disordered individual screwing it up for me anymore. Crisis? What crisis?
