Sorry HBH. You will have nights like this. Read around detaching is very very hard. I don't know if anyone truly gets there.
But while she is in the house, you have to "Fake It". It is impoortant that she sees you in a good mood. If you can't do that get out of the house. Go for a walk, a sports bar, a coffee shop, the library, a movie, something you enjoy. Get yourself back to a place where you can go back to your wife with a happy exterior.
People are drawn to those that are in a good mood. So your W will be more likely to open up if she always sees a happy HBH (even if he feels like s*&t on the inside).
