Well understand that she is looking for SPACE. And when you didnt give it to her and do as she wished she, monstered on you.
Good job not moving out of the bedroom.
She may move out at some point and you will not be able to stop it.
As far as the MC goes, I guess my opinion is it depends what it costs. If it is the same price as a DB coach maybe you would be better doing that instead.
She is not going to MC, so it is for YOU right now.
Do you have EXPECTATIONS from counseling?
You can only CONTROL your 50% of the marriage, if she doesn't want to be in it then no amount of counseling is going to force her.
DB'ing is counter intuitive. You must LET GO and any amount of pursuit will drive her away.
Sometimes just our voice, is considered pursuit.
You are still very early on in this and my basic advice is to lower your EXPECTATIONS to zero.
