The Alcoholic in My LIfe

My boss is an alcoholic.  He almost destroyed himself 19 years ago because of his addiction to alcohol and cocaine.  He got sober and remained that way for 19 years.  Last fall he decided that it would be okay to have a glass of wine now and then.  Since that time, he has been in three rear-ender accidents, totaled two of his cars, and is facing a drunk driving charge.  
I have also noticed a decided difference in his personality.  He alternates between Mr. Nice Guy and Mr. Bully

His wife phoned me at home at 7:00 a.m. when he was arrested for DUI .   This morning my phone rang at 7:00 a.m. and his wife told me that he had been arrested last night for domestic violence; had bailed himself out and come back to the house and was again arrested for violation of a restraining order (which had issued automatically when he was arrested for DV).  He is now sitting in jail with $100,000 bail.  He is to be arraigned tomorrow morning at 8:30 a.m.  His attorney is hoping for an OR (own recognizance) release.  His wife is willing to drop all charges if he checks himself into a 30 day residential treatment program.  He is not agreeable to this.

If he doesn’t go into a residential treatment program, I am afraid of receiving that third 7:00 a.m. phone call from his wife informing me that he has wrapped himself around a tree or killed someone else.
