You can wish all you want, that will not change a thing, nothing. It is all up to him, he is not in recovery, he is white knuckling it, and already has started drinking,I would say that you can expect another DUI, maybe two before he wakes up, and there is a possiblity that he may never get it.
I would strongly urge you to start up Alanon meetings again. Even if he does not get healthy, it doesn't mean that you shouldn't.
