My mother is one of two alcoholics in my life. She has been drinking non-stop for 65 years, one drama after another, one ruined holiday after another.
I am no contact with her for the third time in my adult life, once for ten years,thus far for a year. I am done, I will not fold this this time, it was her or me, I chose me.
If a person does not want to quit and embrace recovery, there is nothing you can do. This is a
progressive disease, that, without recovery for life, has no cure.
IMO, the key is to let go, turn him over to the HP and go forward with your life. Have you read "Codependent No More" by Melodie Beattie? Been to any Alanon meetings? If not, I would
do both. Also, read the stickeys at the top of this page and the Acoa forum...finally cynical one's blogs. All of the above will help.
I am sorry that you are going through this, I know how painful it is.
