The modern way seems to be for couples to have a joint account for all the normal household expenses, like gas, lecky, Council Tax, etc, but for each to have their own accounts, for their personal spending. You can have as many bank accounts as you want these days. I have two with the Co-op bank, and one with Tesco, as I have three different employers.
Direct Debits have made everything so much simpler. I advise that the two of you set up an identical DD into this joint account every month, say £500 each.
Also think about setting up a regular DD into a joint savings account, to pay for holidays.
If your new hubby isn't very good with money, and not everybody is ( ! ) then I am sure he will appreciate this simple but fair arrangement. Your DD into the joint account might be more than his, if you earn more, but the principle of sharing the expenses is an important "red line" issue !
