Married, 4 kids, she’s stay at home mom.

Joint checking, savings, investments, home ownership, cars, everything. I do most of the account management and planning because she hates doing it.

We have no concept of fairness in spending. If she wants something truly expensive we talk about it and how it fits in our budget. I do likewise, but in general we both kinda know what the boundaries are, and there’s zero score keeping. She probably spends 3x on herself compared to me, and I’m fine with it. I know she has the best interests of the family at heart.

Large purchases like cars are the result of weeks of research, discussion, planning, budgeting, etc.
