Desirous
Action expresses priorities
I would never live with someone I'm not married to. That's a financial risk right there and the only time when who makes more money should be an issue. If one person has more debt than the other, they have to be responsible for not only their portion of the shared bills, but their individual bills as well which sometimes impacts how they pay their shared bills depending on how much money they make.
I see it no different than having a roommate. I'm living with my best friend at the moment and her individual bills are her business and vice versa. We pay rent, cable/internet together and that's it. The cable's in her name - soon as she gets the bill, she pays it and then I e-transfer the money to her within a week. When rent day comes, she writes one cheque with her half of the rent and I write a separate with mine and we submit two cheques. She has her student loan, I have my mortgage and what we individually make doesn't impact our living situation.
