He should make dinner.
Assuming you both work etc, the one who isn't too tired or late getting home should start dinner. If has stopped doing that, could it be that he wasn't doing some things "right?" My DW ruled the kitchen while she was a SAHM. When that changed, she had to relinquish some control over the details. When I'm cooking dinner, it's done my way. If she wants things done strictly her way, she gets to do them. She's that way about doing the dishes. She won't let anyone else do that. I'm ok with that. If she changes her mind on that, I'll do dishes
