I would also add, as the child of an alcoholic, that there is always hope that the nightmare of living and loving an alcoholic will just STOP. That it's the last time or period of "moderation," and their alcoholism will be "done." I found that, like I said above, my only possibility of recovery in my relationship with my mother was when she finally quit drinking for good....and that came well after various one drinks here, a couple there such instances or short phases that I ALWAYS knew were going on even if I confronted her or tried to convince myself it was really OK.
Just my add'l $0.02.
