You are on the right path DDJ. I see your strength and resolve. I applaud you for that. It won't be easy but you can do it. Definitely read the book and don't let her see it. If you need to drive somewhere and read the book 30 minutes at a time, then that's what you do.
My W also had/has a problem with alcohol. I wouldn't call her an alcoholic but that's where she runs when she gets overwhelmed. But that's not a healthy way to deal with issues. There is a difference between wanting a beer after work to unwind and needing 4 or 5 or 6 because you are having a hard time dealing with something. The latter is trying to escape and we have to deal with our issues, not run from them. I think you need to set a boundary on the drinking and make it a firm one. What will be the consequence if she breaks the boundary? There always have to be consequences.
