I liked it. I read many of your posts. I think you offer wise counsel. I don't actually need it because I am not in a crisis marriage. However, I once was.
The crisis started 40 years ago and was a 10 year ordeal. It involved infidelity on her part. I was the leaning in one and she was the decider. In the beginning, I made most of the mistakes that you describe. Then things took an unusual and unexpected turn. The situation went beyond anything you have ever written about.
I have published the entire saga here on Medium. It is a long story and you may not have the time or patience to read it all. If you'd like to take a look, it starts here:

At the end of the ordeal I'd had enough. Neither of us wanted to continue the marriage. I am grateful because it turned out well for me. I think it turned out well for her and our daughter. All of us are living lives of contentment.
