Honestly, his words are alot of mumbo jumbo, whether he feels he is physically addicted or not doesn't change a thing, he is a binge drinker, he has just gotten a DUI, he as a problem. It still sounds like he thinks that he can resolve this on his own, he has proved that he cannot.
I always go back to the children and the negative impact that his behavior and your reaction to "his" problem will have on your children. They will carry their childhood into adulthood, they do not miss a thing, they feel, hear and see everything.
Unfortunately you cannot force him into recovery, you cannot control him. IMO, the real answer is to set a boundry with him and stick to it, say what you mean, and, mean what you say.
Until you both get healthy, I do not see anything changing.
Hope this all works out ok for you and most important, for your children.
