People giving you trouble cause he’s only 42 haven’t seen how miserably useless some grown men are when it comes to household stuff. I did similar for a while to save up for a house, but in my case he was also an alcoholic so it’s doubly difficult. Having moved out, he’s struggling to feed himself though.

I think caretaker is the right term, though. House-anything is weird sounding, though (housewife for instance is out of favor for more gender neutral terms).
