Its a very interesting thread!
I am in AA and have a few good friends, i've alway said that if they went out drinking again i would still sit with them and, with these few, our friendship wouldn't suffer...i could only be there for them for when they were ready to stop of course...but like i said i am in AA and these are AA friends...i'm an alcoholic and so are they?
How many times is too many for a non-alcoholic...honestly i would say one, why stick around for the next time, if i can't stop one of my friends drinking with the solution at my fingertips what chance would someone without a solution have?
I find it very ironic that i would not put up with a partner who was in active addiction even though many partners of mine did...maybe it's because i know how futile it is and was to be involved in any way shape or form with the addict/alcoholic all the while they have little or no intention of getting help to recover?
Just my 2 cents anyway:-)
