GB- If it makes you feel any better, my H completely checked out for over a year. He literally did nothing around the house - did not do the lawn, change a light bulb, nothing. Forget out cooking or cleaning.
A few months after my H moved out (and going on two years of him being MIA), we were doing something as a family and then I went out with the kids for the evening. H was supposed to head out separately that night as well but evidentially he stuck around the house for bit. When I came home, the entire house was cleaned. I actually thought to myself, did someone break in and clean instead of steal everything? He made the kids beds, but away laundry. In 15 years, he never did that. I was shocked.
