I currently do all the cleaning, but when I raise it, DH takes offence and insists he does help and says that I just 'don't see' all the things he does. I suspect that all he does is sometimes take the bins out or throw something away that's gone off in the fridge.
To that end I was thinking of writing out all the tasks that need doing at least weekly on our chalkboard, and suggesting we tick them off when they've been done to keep track. If he really helps as much as he thinks he does, then no problem, he will find himself ticking some off. If (as I suspect) he does almost nothing, hopefully he can then visually see just how much I'm doing compared to him.
What have others done that seemed to work?
P.S. please no unhelpful posts along lines of 'get rid of this manchild'. People don't realistically end otherwise happy marriages because DH is averse to a duster. I'm sure there are things he'd change about me too.
