I would suggest that you seek out help from your local Al-Anon and start focusing on yourself and what you can do to recover from co-dependency.
Just speaking for myself, the devil nor spiritual weaknesses have anything to do with a person's alcoholism. It's a disease and many people have a predisposition in acquiring it.
No one needs the drama and heartache that you are experiencing...life is too short
Seek out help from a 12step group, friends, and family.
My best to you...there is a lot of support here at SR
