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?
Surely there are no hard and fast rules in any relationship. It works for some, and not for others. Instead of looking for a universal rule, from which to judge the 'quality' of your relationship, you need to communicate your needs and opinions to your SO and come to a mutual solution. You also get to decide if that solution is what you need in an SO. Surprise, so does she. Incompatible means incompatible, unfortunately, but better to get it out in the open and part ways amicably than get burdened with a civil union and a messy breakup.
