Honestly never heard of anyone with this arrangement .. either the man handles it solo or they do it together. No reason a woman couldn’t do it but just haven’t encountered it before
women hold around 70% of consumer spending
So on average the woman decides what the money get used for in a marriage.
If thats true why not just let her have the purse strings?
My wife and I just have "money" we dont have mine and yours.
I have a personal account for my salary and some bills taken out , my wife has the majority of the funds in ISAs , premium bonds and cash accounts.
The house is paid for so no mortgage
If she wants to but things for the house she asks me and I say yes, I couldnt give a fuck what she spends it on, I know she isnt an idiot and is going to blow it all
Its a much easier life for me
