Ah hard one.
DF and i have had joint bank account since forever..At the time he was living in a apartment i rented, and he gave me part of the rent etc, and if he ran out of cash i would give him money ,we decided it was to hard, we got an account together and our money was 'our' money..( I still look after the money ) lol

I think its a bit hard on you if the money you get all thr food and bills goes towards..what does the money he gets go towards?
Would he sit down with you and talk about all the bills/food/expenses/ day to day odds and ends, and both of you work out a budget maybe? Then you can work out what money left over is 'spending money' for both of you?

This is just IMO but i just feel its easier and what you do sort of thing when you are a couple, you share everything including money.
I think he needs to understand where your money goes towards so he knows that you are paying for a lot ITMS
