First, sorry you find yourself here with us. This is a great place for support. I can pass out compassion, but I assume you want results. I will give you my insight.
Reading your post, 90% of it is my story. So I will give you my input based on what DID NOT WORK FOR ME and what I have seen WORK FOR OTHERS HERE and insight from over 40 books.
Coach and Robx are very wise. I highly suggest you go back and slowly reread what they are suggesting with an open mind. The sooner you follow their recommendations, the more likely you will see positive results.
What works is counter intuitive to what you want to do.
My first mistake was moving out of the master bedroom to give my wife space. I strongly suggest to move back in immediately. No advance notice, no asking. When she brings it up, you will say:
"I have decided "that I prefer the master bedroom."
She can say whatever she wants, you just listen and validate (3 to get you started): "Yes, I can see why you would feel like that" "I can understand why you would feel like that" "It must be hard to feel like that"
