I do sense that I am being hammered by the MC and my wife more than she it. We tend to talk about what I'm doing wrong because I have been resistant to the ideas.
Seems like you have a great opportunity here to identify what things you need to work on for 180s. I would encourage you to not be defensive and resist. Listen to what your MC is saying with an open mind and work on fixing them. Reading through your thread, your W seems to be sincere in making the marriage work. However, you need understand that it is not easy for her to do that given her current frame of mind. It is also possible whatever you do now may not be sufficient for her to reconcile but you only control you.
WAS have a very different perspective on things and it is often disconnected from reality. That should not discourage you from learning what you did wrong and fix that.
