Family Issues Support Group
Family issues is a huge range that go from minor conflict to major misbehaviour and even abuse on the part of individual members of the family occur. Whether you feel you are in a dysfunctional family or you're dealing with a very specific issue, this is the place to talk about it and find others who might be going through the same thing.
Then go over to the D.S. board for Family & Friends of Addicts (they are for all types of addicts, including gamblers) and get on that board and learn. Addicts are born liars.

Unfortunately, while you are still married, any loans or cc debit that your husband acquires is also your debt to pay. If they can't get monies from him, they'll come after you. The only way out of having the responsibility of his debt is to get a legal separation. Anything after that, is his debt and his debt only. I'd do what ATG stated and get a credit report done soon to see where credit rating stands today.
Addicts of any kind will do whatever it takes and go to whatever measures they need to, even to the extreme to obtain what they need.
I would definitely seek out legal advice and soon.

Yes, it depends upon the state. I'm sure I read that if you can prove that the debt is only the one spouse's, then the other can't be held liable, but it may vary from state to state.
