whether he thinks that or not is of no concern to you. Tell him you are allocating the dishes as HIS responsibility... since you are doing all that you are doing, and that it is up to him whether he washes them himself, or hires and pays a woman to do them... just to let him know, he'll have to first earn some money of his own before he can pay her.

Put your foot down... you have another sixty odd years of this to go!!!!! Do not set the bar of expectation so low. You will regret it many times over.
