I would try sitting down and talking with him. He needs to remember that you're not his mother and that this is a marriage, a partnership--not a master/slave situation. I would calmly and politely tell him that as part of the marriage agreement, you have the right to expect his help. And if he doesn't start helping, then the things that won't get done are the things that he needs (as others have mentioned)! Then I would point out that you know he hates your nagging and you don't like it either, so from here on out you'll stop nagging him. But then firmly remind him that when he refuses to help you when you ASK (or even when you don't), he will be the one that suffers!
This is essentially drawing your boundaries and sticking to them. You can only control you, so take care of your business and let him suffer the consequences of neglecting his!
