It sounds to me like your husband is making the point that when he is WFH he is actually working. So you need to do things his way so he understands.
So when he is having an evening off with his sport, make sure you also have an evening off. Don’t do any housework - go out or relax at home. Make sure you do nothing else. No popping on a load of washing etc.
If all these things are too much for him to do when he is relaxing during his lunch break, they are too much for you on your night off.
If he doesn’t do housework when he’s working, neither do you. No shopping or wifework at lunchtime or on your commute.
Likewise you need to stop all this malarkey of his chores being shared and your being your sole responsibility. As a PP said, divide them up.
If he doesn’t do his, you don’t do yours. It takes some planning on your part to make sure you can do this without the kids suffering. Most men who play this game rely on the fact that you will sort things for the kids and that you care more about the mess so you will give in first.
When you come home and things aren’t done that he should have done, DONT DO THEM. I’ll admit this is REALLY HARD, it takes an iron will and far more effort than actually doing it. But it’s the only way he will learn.
He will continue doing exactly what he’s doing now as it works for him. He doesn’t care that it not working for you.
There’s nothing wrong with his eyesight or memory, it’s his sense of entitlement. All the talking and explaining and agreeing in the world won’t change this. You are fighting 40 years of conditioning that says it’s all women’s job and if a man does 20% he’s a hero.
The only thing that will work is YOU changing what YOU are doing and when that adversely affects him.
