I don't excuse the attitude, but I do think It's fair to point out that your retirement is a major adjustment for you both as a couple, not just for you.
How was housework split between you before you retired?
What is his input on the weekly menu? Have you made any of his favorites? (note: this is our tactic for our kindergartener. He gets his turn to pick, but then no excuses for more exotic things)
Is he a grill master, or can he contribute to cooking in some way? (note: not used with kindergartener)
Did you have any prior stay-at-home time (parenting?) that may have set expectations?
How much of this detail did the two of you discuss beforehand? Is reality significantly different than the discussions?
So, just trying to keep an open mind to things. Really, this sounds like it could be the complaint of any housewife / SAHP. But probably, It's time for some counseling--particularly if you had not had discussions about housework / expectations beforehand.
My wife has been stay-at-home for 19 years due to health issues, then our child. When I retired last year, ahe clearly expected me to pick up some household duties. And that is only fair. While I actually enjoy a number of them, (e.g. cooking) and took on a good deal, I had not met her detailed, unspoken expectations. She had in mind sort of a 50/50 split of each line item, where I have things I do (garbage / vacuuming) because I am better able to do it, one way or the other. We had a major reset after about 6 months, because she had building resentment. And we both know now to communicate more openly about things. It's hard to try not to tally up a "score," whether based on tasks or time, but to reach a point of fairness / balance. It will probably be even harder as we expect our child to contribute more, because we probably *will* have to have some sort of recordkeeping mechanism.
By this detail, I just mean to say it isn't falling down easy. It is one of the adjustments of this major life change. Everyone should put due effort into understanding and managing this aspect of the change.
