Well this guy was a pharmacist (they make over 100K), I am not sure what his wife did for a living. I suspect, nothing. To have to ask to use your own money is insane.
Anyway, I guess people who get married young do have shared account. But I am 39 and it will be a cold day in hell before some woman assumes that she can have access to everything I have worked hard to save)))) You should always contribute and help, but please keep your money separate, unless you want to lose everything you have worked hard for (divorce, wife overspending do happen and they happen often)
Our mindsets are completely different, which is fine.
I totally get what you're saying and there probably is some truth to the age thing. You're so used to being on your own way into your adult life that it'll feel so foreign to share money or have to answer to someone about spending what you worked for. I get it. That's cool.
