You have some very wise folks keeping an eye on you.
I am not one of the wise, but I would like to offer some support.
If things in your M were to improve, what would you need to see from her? What would she need to see from you?
If things in your M were to completely fall to pieces, would you be willing examine your part in it? What concerns has your W mentioned that you feel are valid?
I wish you the best of luck, sir. God bless you.
One last thing, if you and W find yourself seriously trying to salvage your M, she should change her place of work as soon as possible. My W's EA/PA found its roots through the workplace. We spent a lot of time talking about it, time that we should have been using to focus on us. It was difficult for me to let it go while she worked with him and I am sure it continued to be an A while she was working with him.
