Unless you go the trad, Islamic route and say, "Yeah, this is my domestic slave." I think that sucks even more.
You're thinking a little too hard about it, and it comes off like this nickel and diming is gonna kill a relationship more than the financial asymmetry itself. We've talked through expectations through the relationship and what happens if we break up, and we're both happy. You have so many question marks I don't know what's rhetorical or what isn't, but no, she's not gonna be homeless if we break up because she has a career.
> you are valuing her to some amount you made up (together?)
We just pay for rent and shared expenses proportionally to our income. We don't monitor it super closely, rent is always your biggest expense, so it's not a big deal if I pay for dinner once or she does.
And to say my relationship is unhealthy because of this really shows your world view. Maybe a relationship is all about money to you, but we value each other for reasons beyond that.
