Do you and your husband have all you money together?

I just got married last month and this is a big problem. My husband wants us to combine all our bank accounts. Right now its set -up as "his" "mine" "ours". I have my own savings and he does too and we just put money into our combined account every month for household bills.This worked great when we were engaged but my husband said he has never heard of married couples doing this and wants all our money put into joint accounts.Heres the problem that i have with it, he was married before and has a child that he spends tons of money on to the point he can't pay his c.c bills.I don't mean to sound like a evil stepmom but if he wants to go into debt so jr. can have everything he wants let him do it with his own money. I just need to know what you guys think. I'm just afraid if we pool our money he will see it as free money to spend as he wants.So do any married couples out there have a bank account in just their name?
