Thank you for writing in to Just Answer.
I'm so sorry to hear about your situation. It is certainly not an easy one.
From what you describe it sounds like you really have to start putting aside some savings so that if things get worse you can separate from him and live independently. Are you currently getting a salary for your work at the bar? If not, I would recommend that you insist on one which you can put aside as your savings. Since it doesn't sound like your husband is open to seeking professional help, I would also recommend that you expect the worse and look for jobs for yourself. It is clear that if the situation does not improve you will need to move out of this relationship as it can become stressful to the point of damaging your self-esteem and impairing your functioning.
You can consider joining a support group (if you are able to step out of the house without him) - for the spouses/partners of alcoholics. Also, often universities that offer counseling degrees will have clinics where doctoral students will offer very affordable counseling so if there's a university that offers a counseling degree in your town you can contact them about free or reduced fee counseling for yourself as I think that will be very helpful to you.
You can also try to talk to your husband about acknowledging that he has a problem and then seeking help for it, and if possible you can lay down some ultimatums that if he doesn't seek help you will consider ending the relationship.
In terms of books/resources - here is a book
that I think you will find useful.
I hope you have been able to provide some direction. Please do let me know if you have questions/thoughts.
