Your mom has stayed with him all this time? Whether he’s drinking or a drunk or just an asshole, whatever the hell you call him (who cares about the nomenclature?), she is enabling his shitty behavior. If she keeps doing it (or his other enablers, if your siblings/his friends enable his assholery), he will never change. It’s possible he’d never change anyway, and just die in a gutter, but you can’t find that out unless you remove the enablers. But you cannot stop other free-willed adults from enabling your father, and you should not feel responsible to even try. This is the kind of problem that trained, licensed addiction specialists (who aren’t related to the victim) get paid thousands of dollars to help with!
All you can do is cut him out of your life (awesome job on that) and recommend it to others. Demonstrate and rave about how much happier and more stable you are without him in your life, and over time that might convince others to do the same. But the responsibility for his drinking and assholery are NOT ON YOU, as long as you’re not enabling him. You could talk to your mom about leaving him, but I wouldn’t bet a wooden nickel on that.
Anyway, it’s one thing for internet strangers to say all of this, and yet another thing for you to believe it. Get some counseling!
Don’t rely on AA. Based on statistics provided in an episode of Penn and Teller’s Bullshit, AA is no more effective than other methods of quitting drinking: the 12-month sobriety success rate, with or without AA, is 5%. But with AA, members are fed a bunch of quasi-religious quackery about how alcoholics can’t be in control of their own life without fucking it up–talk about fucking insulting. And most importantly (to me at least), AA is NOT open to atheists or people who feel that they are in charge of their own life. :rolleyes: Check out the orange papers if you’re interested in criticisms of AA.
Now, if you don’t feel in charge of your own life, and are strongly religious, and aren’t an alcoholic trying to sober up, you might get something out of an AA meeting. But it’s nothing you won’t get more of from a session with a trained psychologist. You might say “AA meetings are free!”, but that’s still too expensive. You could not pay me to attend an AA meeting.

Your dad beat the odds on alcohol addiction once, but it doesn’t seem like he wanted to stay on that wagon–which is his decision to make, nobody else’s. Unfortunately, your mother did not stand up to him when you and your siblings were young enough for it to matter. She may be exhibiting battered-woman syndrome, for all the good it does to label her. And all of that shit is unfortunate, but you STILL can’t change it.
Sorry, I’m rambling.
