You obviously love your wife very much but as others have said, you can only really help
you. Focus on yourself and staying sober using all of the methods you can. When she (if she) talks to you about it, then you'll be able to talk to her about your experiences so far.
You'll probably get a great deal from reading the book yourself, so read and leave it at your bedside as you would any other book.
Drinking one and a half bottles a night does indicate that she is an alcoholic (and to my mind questioning the difference between an "alcoholic" and an "alcohol abuser" is just word-play to keep denying the hard truth
)
Keep up your good work, 10 days is pretty awesome.
