I don't know if my wife is in a fog, or just in denial. She says she feels that way.
So she feels like she is in a fog or in denial?
Either way those are her feeling, NOW! Have they always been that way? You seem to assume that her feelings now will NEVER change. That is an expectation.
IMHO, and this IS mind reading, she IS in a fog. The fog WILL end. When? I can not say. But DB101 will help you get past this time. Leaving your home may not.
Detaching, living your own life, loving her from a distance. That is what you must do.
Not pressuring, controlling trying some tactic to win her back. There are no tricks in this.
More about the FOG. If I told you she was sick and had a terrible disease would you leave the house? Would you have more compassion for her? Pin, this is not about YOU, it is all HER. Until she comes out of the FOG, you must do DB101. Patience is the name of the game.
Instead of moving out of the house how about being NC/Dark/Dim? Treat her now just like she does not live there anymore. Or like you don't live with her anymore.
