You are not detached enough. If you are thinking a new job and a new location would be what your M needs.....I would discourage it. Those things could actually add more stress. If you see it as a way to pull her away from OM, it won't work.
What would your decision be if you were D from W?
Here's the thing.....you haven't decided yet and you are hoping that she will agree to all of this. You are hoping she will wake up and realize she doesn't want you to move away. Unless she was to have a falling out with OM....she will not want to move. Don't use this "opportunity" for a job change as some tool to pry your W in your direction.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
