Should household chores be 50/50 too?

Personally, I wouldn't have it any other way between me and my fiance. But you do you. Relationships all work in their own ways. His grandmother does all the household chores and cooking, but they both work full time; and they seem happy enough with it. Maybe he just folds all the laundry wrong and she can't stand it. But personally, if my guy isn't pulling his weight, I complain about it. I believe if you make the mess you clean it... which I suppose comes out to 50/50.
