Not sure this is much different but:
I'm a decent amount older, and was much more established when b we got married. My net assets weren't much, but just out of school she was significantly in the negative. She also had never really ran her own finances, and I obviously had.
We joined all our accounts immediately. It's Worked. Particularly because she moved 2000 miles when we got married, it took her a year to get really good work from local contacts. Then we had our first kid and my work was able to go flex time / evening hours, so I did that with a big pay cut while she worked full time. After kid 2, she wanted to stay home and do I took an 80hr/wk position. So we have gone from me making 90% of our income to 50/50 to her making 75% to 50/50, to me making 90%, and then down to where now I make about 66% of our income. Joint finances helps. We talk about being a team, and setting our team goals, and making sure that both individually and together our money is making us happy. We are very happy with this. Also, we both do lots of contract work, so we like not having individualized contributions. One danger we realized it's if my income growing increased my bill %, it gives me incentives to not sell out gigs as hard and free-ride (obviously same with her). Being fully integrated makes it easier to take on extra tasks (not always easy - we both tend to want new toys to "help get gigs").
Logistically, I control our finances, our accounting, our bills, our taxes. I generally try to balance our retirement accounts so they are somewhat similar balance wise. She picks her investment choicesb(she says do what you do, but I make sure she chooses), I pick mine. Mostly this is because she dislikes finances, and I get great joy out of doing it.
We always talk before buying anything besides groceries, gas, or emergencies (having a friend who is sad and wants to go out counts as this), and always frame it in encouragement/discouragement ( I want you to buy that new kit, it will help and is well priced; I don't think you should join the happy hour, they go 4x a week it's extensive and there's nothing to celebrate). So we each get to feel like we make whatever choices we want, and we both mutually shame a bit, but we also feel quite autonomous and committed to the team.
