Hello Hope,
Ditto to all of the above. Especially to JT's statement...
You can protect what is left of your finances if you really want to. Think about it this way. By supporting him you are buying his liquor. You might as well be driving to the liquor store yourself and stocking up. If you stop he will find another way...maybe work perhaps?
Many of us have been in this same situation. At times, it gets twisted around to where they make us feel we just HAVE TO do what they want us to do. Then the guilt trips and blaming. You've been to meetings and have done the work. You know what needs to be done.
Try attending meetings with a different approach. Don't think about him and what you hope for him. Focus on yourself and what you want and need for yourself.
Blessings
