Well, in my case- my EA fell apart- thank God and I suddenly knew what was missing in my M...the day W "checked out"- was the day everything changed...
It may be risky- but like everyone says on these boards...you have to become the WAS- make H the LBS...thats the nature of things...
In my sitch it really can't work...evern if OM wasnt in the picture...W worked 7 days a week and surrounded herslef w/ people I didn't know...
She complained to them constantly of me and told them how selfish I was w/ our budget, and the fact that I would play golf on the weekends while she was working truthfully, all I wanted was for her to take weekends off so we could be together.
My point is that if your H has assassinated your character to MIL and already surrounded himself w/ supports- it may be tricky...BUT- I did that as well...complaining to friends about how disconnected I was from W and how difficult our life was b/c of her business.
AGAIN- when she checked out- told me she was done, started dressing up all the time and going out w/o me...kept quiet and mysterious at home, moved into the other room, switched bathrooms, etc, etc...
I immediately wanted to work everything out...MC, pursuit- I KNEW WHAT I WAS LOSING- I KNEW OUR PROBLEMS WERE MANAGABLE
I guess that's my advice- and the odds are in your favor b/c you're a woman
