Joint bank accounts with married couples?

How should I feel if my husband doesn’t want a joint bank account? He says “he doesn’t want anyone telling him what he can and can’t do with his money”. I’ve never told him what he can and can’t do with his money. No I don’t need his money, but I feel like when you get married to someone, your things now become both of y’all’s things. Am I the only one who thinks that? Or am I just over thinking?
