Should this be an issue to be concerned about?

I have a boyfriend of over 2 years, we handle money differently he does not know how to manage it & it worries me that once we move in together or get married things will go downhill for us financially. Like he has told me that once we live together he’s gonna keep a little bit of money for the week & let me handle the rest. Is this something any guy does & it’s normal? I’m just not sure since I’ve never lived on my own with a boyfriend & etc..
