I'm sure with the hours that he works the last thing he wants to worry about when he gets home is cleaning the oven and the living room. But he has to understand that you also work 8 hours a day sometimes and you don't WANT to clean but it something that HAS to be done. Maybe instead of nagging him you just sit down and explain that you understand that he works hard and doesn't want to clean but if you work together it gets done faster and you won't nag him as much.
