I don’t think my partner would mind. It’s all combined anyway.
I think it would only be an issue if I made enough to buy the things I want, but he didn’t make enough to buy the things he wants/needs, so he’d essentially have to ask for my permission/consent to do his thing. That frustration of course would go vice versa if I didn’t make enough money to do what I wanted/needed. It’s especially an issue when the person who makes less money has wants and needs that interfere with the wants and needs of the person who makes more money.
