What worked for me and I learned it from reading it somewhere in the vast resources at this site, is what I call "Playing 'Possum." He could no longer get a rise out of me, get the reaction he desired, feed off my pain.
When he did those things intended to hurt me, I looked at him and calmly said, "That confuses me, I think I need a nap." Then I walked away and put myself on time out.
Yes, he escalated, he manipulated, he spun out, he destroyed things, he left in the most hurtful way he could think of, but he left. He found someone else before he left. He left on our 17th anniversary and it was the nicest thing he ever did for me. My health and happiness is restored.
Good for You.
I'm working on my own health and happiness, right now. Thanks for YOUR inspiration.
I've been 38 years in this relationship, 32 years married. A massive decision soon to be made.
Love was not enough. Hard to understand!
