We each have a personal account, apart from these we have a joint account into which we pay a fixed sum every month to cover utility bills, insurances, mooring fees for our boat, DH's trade union dues etc., all of which are paid by direct debit from that account.
We both know all the details of our finances, I deal with paying the household expenses and decide how much money we can afford for that each month.
Any major expense, or indeed any expense that cannot be paid from our joint account or the housekeeping is discussed in full before one of us uses the money.
Our bank loan and mortgage for the house is DH's business to cope with, as I freeze when confronted by sums of money with lots of noughts, but again I know all the details, just as he knows what our utilities, insurances and housekeeping amount to.
I don't know that this will be of any help to you, as I suspect your DH feels that as he earns or earned more than you, he is in charge of money matters. But like most of the others, I hope you know what he is doing with the rest of his money!
