I’ve seen couples support each other taking turns going to school, but there was the expectation of becoming a dual income couple and even then they were together as economic equals beforehand

I can think of one or two couples where the woman was a high level executive with a broke artist waiting for their big break. I would actually dare extrapolate that to an extreme where highly economically unequals get together.

But I want to see something more mundane. Like a single earning woman is a UPS driver keeping a man that is so enamored with her ability to provide. Because I’ve seen that with the gender roles reversed, and that attractive woman could have been a live in partner with anyone. This would not be predictable for men in heterosexual relationships right now.
