Alcohol and addiction is his answer, my behaviours completely changed around alcohol, how much was in my glass? how little was in my glass? how can I hid my drinking? how can I sneak an extra few drinks? It didn't matter what else was going on, a wedding, a birthday, a celebration, I would become consumed and obsessed with thoughts of alcohol.
As others have mentioned you can't really explain that to someone, it's gonna be more a case of actions speaking louder than words, getting a plan in place to be Sober, being proactive and making Sobriety happen, in time he'll come around!!
Hang in there!!
