A girlfriend of mine is married to a guy who is having a hard time dealing with the fact that she makes more money than him. A lot more. Historically he has not proven himself to be the best money manager so they now have separate bank accounts. From the way it sounds, he thinks that she has millions stashed away. In my mind, even if she did ... so what? She earned whatever is in her account, the bills are paid and she is working to keep them out of debt.
What's the problem? Why is this even an issue? If you're married and you're both working and all the bills are paid what difference does it make from which pot the money comes from? Why do men get "funny" when women make more cheese than they do?
Personally, when I was married I tried the joint bank account thing and it just didn't work. It was my responsibility to pay the household bills but I couldn't keep track of what was in the account because he was always making unnecessary withdrawals. Why? So he could have money in his pocket. After I heard that excuse we got separate accounts. I know people who can make it work but I wasn't one of them.
