Marriage is about coming together and becoming one. If you can't trust one another with money, you shouldn't be together. I mean, you'll sleep beside someone and they could kill you in your sleep nightly, but "my money" and "your money"??? It probably helps my wife is my sugar momma
Seriously though, we've known each other since college when we didn't have money, so anything we've built has been together. I guess if you meet later in life, have been through divorce or something, I guess I could see it, idk.
