Have you read any posts on the Friends and Family of Alcoholics section of the forum? It's eye-opening. Our loved ones experience a lot of frustration, sadness, dissappointment, and anger because of our drinking, especially if we've been drinking for a long time.
I think in this case actions will speak louder than words. Show him you mean what you say. Let this be the impetus to grab on to sobriety and never let go.
Best to you,
