I can understand it may sound rude to others but generally a house have, explicitly or implicitly, roles distributed among members, and every part is supposely to perform it well, or negotiate for a new assigment so not burden one part more than other.
I do give some substantial money help to house. And I dont actually have a problem with preparing my own food. Actually, I used to do it quite often before pandemic but the problem is, everytime i started do it, my mother comes and do it before, like she own it. She does good till i gave up the idea preparing food, so then she slack it again, rinse and repeat.
And its not like im demanding she to do it. I never once complained about this and most likely never will. But that doesnt mean Im happy with this situation, and even more unhappy i cant change it before messing with her pride or whatever.
What percentage of the mortgage and property taxes/home insurance do you pay?
If it’s over 50% yeah she needs to understand your concerns
If it’s less than 50% or the house is paid off yeah sounds like time to find your own place and peace.
