Here's an idea that I used years ago.
Sit down together and make a list, that you both agree on, of all the chores in the house. Every last one. But make sure you agree.
Then, deciding together you assign a numerical value to each. Make sure you agree.
So he might like hoovering, but think cleaning the skirting boards is awful. It doesn't matter. Agree with a number.
Tear them all off when you're finished, screw them in a ball, put them in a hat.
Take turns picking one each. At the end, you have to make sure you have the same numerical number. You might have to do a bit of swapsies if one of you really hates something but the other doesn't mind.
But the number should be equal. It might require a little bit of tweaking.
That way the chores are divided, on a pre-agreed value of each chore. With you both ending up with the same. But he hasn't been able to wriggle out of anything, or assign a bigger number to something he hates, in case you get that number or vice versa.
It's the equivalent of dividing a Mars Bar in half. You cut, I choose.
If nothing else, he will be aghast at the amount of chores that have ended up in his lap. Even though he has explicitly agreed on the value and equality of those chores.
