I used to know a couple (late twenties/early thirties) who were married and lived together, but they did not share finances. Everything was divided completely in half, like roommates do. And like roommates, if one couldn’t cough up enough money to pay their half of the rent, too bad. They had to resort to extra shifts/ selling stuff. 

I’m all for the arrangement in theory, because people can keep their money however they want. But in this instance, one partner made significantly more money than the other, so while he was buying PlayStations and eating out and doing whatever, she was always struggling. (She was trying to become a full time artist, and doing other work on top of it. This dream preexisted their relationship, so it’s not like he didn’t know about it.) And it seemed kind of cruel to me? Like he had all this money, and his wife was struggling, and instead of sitting down and either supporting her dream like partners sometimes do, or working out a cheaper lifestyle or living situation that would ease things, he was totally just content to sit back and watch it happen? I dunno. It just struck me as very odd.

Damn that is crazy and creepy. 

Most couples I know. Have a shared account and then each their own. Half of each pay check goes into the shared. That's seems to be the norm now.
