Who’s wrong?

Alright, I need some advice from people who live with their SO and one of you pays more for rent/utilities w.e it may be.

My bf and I have been living together for about 2 years and he pays rent ($1900) while I pay utilities( $300-$400) Groceries pet food etc is sort of split between who has more money when it’s needed. My bf makes quite a bit more than I do, about $3200+ a month while I make about $1800. And we each have our own debts/bills on top of this as well.

The issue we are currently having is he seems to be under the impression I need to be more “motivated” when it come to cleaning. So he isn’t coming home to a not clean house. I don’t mind cleaning more, but I object to him just expecting me to basically be a maid and pick up after him because he pays more money than I do. He leaves shit EVERYWHERE and suddenly I’m a horrible disgusting slob because the house isn’t clean when he gets home from work.

So...how does everyone else split up house chores? Does how much one puts into house bills make a difference? Should I try to make more of an effort with cleaning or is he just being dumb?
