Let’s say both the guy and girl make the same amount of money and are both good at and enjoy cooking and cleaning.
Would it be wrong for a guy to want the girl to give equal contribution financially to the relationship if he’s also willing and capable of contributing equally to domestic duties?
In this same scenario, would it be wrong for him to expect her to cook and clean if he’s expected to handle the financial aspects of the relationship?
If this actually needs discussion between you and can not be taken as a given, then the relationship is not on a level that I would recommend joining households.
