Man, am I glad that we have two, soon to be three, kids. That way, you don’t think about money and/or accounts so much anymore. In the end, more important things count in my partnership. What matters more is the mostly shared approach to parenting, common interests, a circle of friends appreciated by both, family cohesion, shared leisure time, etc.! Money/accounts are rather secondary. And truly, we are not big earners, more on the frugal side in many things. But without going again into "which account setup is best for an intimate relationship," here’s a small advantage of separate accounts. I think separate accounts bring some freedom, not having to “lay everything open.” Even though I’m the family’s classic big earner, my wife probably doesn’t suffer too much from the separate accounts. PS: She also drives the far more prestigious car.
