It's like encouraging a cat to start barking and wondering why it doesn't. You had a conversation not with a person but with the bottle (assume he had booze in him, correct?). We alcoholics are self-pitying, manipulative, self-centered in the extreme. We have enormous egos and low self esteem.
What I do know (cause I'm a recovering alcoholic) is that nothing will get better while he is drinking. Also, there is nothing you can do or say that will cause him to stop drinking, although if he looses enough it may drive him to AA.
