I spent the first 2 years of my daughters life as the stay at home dad. It was beautiful. Groceries, laundry and housework was done by 10 AM and the rest of the day was the beach, museums, zoo, lunch dates with other moms. I learned to be a great cook and dinner was always on the table. I missed those opportunities with my next two children, but let me tell you, as a single dad of three all that training was a life saver for me.
I'd sit down with a heart to heart and a few sessions of counseling. Unless you say something things will stay the same and get worse.
Have you cut him off from all intimacy and sex yet? Wouldnt blame you if you have. May as well have a trigger on it because its as powerful as a gun.
