I have a family member who approached finances this way. He made more money than the wife so he said he’ll put in his portion toward expenses and the rest is is to do whatever he wants (it’s his money right?). She worked hard but couldn’t work as many hours because of kids so she put in her portion and had nothing leftover for anything else. He said, welp that’s too bad and spent his money on a truck and tattoos while she ran herself ragged trying to fulfill her half of the bills and use whatever that was left to go toward the kids. This marriage did NOT work out. Kids went without, she burned out, everyone else burned out providing for childcare. But at least he got his awesome truck and a couple sleeves.

So yes, I think you’re wrong here. I believe an ideal partnership pools all resources and shares both the benefits and the responsibilities. Set aside fun money for each of you to do whatever. But the way it is now you’re never going to be 50/50. What happens if one of you gets sick? Does he pay for his hospital bills and you pay for yours? This whole system you’ve got going is wack, IMO.
