I'm so sorry that you're going through this! I think your husband needs help, and if he's unwilling to seek it, you have no choice but to make him leave. In the mean time, I would make sure that you remove his name from all credit cards, bank accounts etc.

My mother in law died a few years ago. The month before her death my brother in law accidently got hers and FIL bank statement (has same name as his father). In the account there was $14,000. FIL is retired and works part-time for the state in a training type job. He bills his hours on a quarterly basis and had just gotten his fees.

None of use knew how addicted to gambling she was. She died on a Thursday afternoon. On Friday we were making arrangements and FIL says he'll go to the credit union on Monday to withdraw the money for the funeral. Monday we all discovered that there wasn't a penny in the account and that the car payments were several months behind. She was a lovely woman with a sickness. Immediately after FIL last large deposit she was taking thousands of dollars a day to put in slot machines.

Please don't let this be you. Don't let his illnesses bring the world down around your ears.
