Even with children we make up charts of assigned work for each one. Maybe that would work best for both of you to sit down & divide up the housework tasks & assign them to the one responsible. That way it would be divided & he wouldn't even have to think about what needing done.....he would be his task & he would know it & you wouldn't have to mention.

I know we want them to JUST DO IT out of the kindness of their heart & be able to think what needs to be done, but in reality, assigned tasks work out best in the long run & then no one feels bad or wonders what they could be doing.

Then if one or the other does get sick, you could specifically ask the other person if they could cover the specified tasks that you have on your list while you recover.
