from my experience and what is stated, alcoholism IS progressive so be wary that his weekends may start to overlap past saturday-sunday.
with that said, as far as enabling goes--well, toward the "end" of my relationship, my xAbf stated "you're still with me so that means i must not be completely bad"... so sometimes us not actively enabling is still enabling just coz we're in their lives.
i didn't clean up his messes or give him financial help, but i learned that just by sticking around i was enabling him.
addiction speaks/thinks for them at some point and normal logic will not work--the extent that they will take to hang on to the delusion so that in their world they are "allowed" to keep drinking will cross all boundaries so that the addiction will always win. this is true until they are TRULY facing the reality of their addiction problems, which is a place many alcoholics do not even reach.
