Hi B1,
From what you write, your W wants you to react to all the balls she sends at you. And, as you are not reacting, she is not happy. So, the MC looks like a way to oblige you to react to the balls. She is totally desperate to make you react, and she is looking for an ally.
So, imho, if you accept this MC you can prepare to the worse and sharpen your best communication skills to not react and listen ; keeping an open mind is a good idea. Don't expect this MC to save your M, if it happens it will be a good surprise.
When I got the MC 2 months ago, my W wanted to separate and was preparing escape paths. But at the end of the MC, even if the mediator asked her 2 times whether she wants to speak about separation, she did not say a word about it. My W is afraid about D and does not wants to initiate it, I guess yours is in a similar position ?
M 43, W42. Married 18 years, together 21
3 children D16, D14, S5
OM discovered Dec 22, BD Jan 23 (few days after)
W still living at home

Love means to give without expecting return, and every act is a prayer if it is a selfless gift. (thanks OffRoad !)
