I don't think what you did was wrong. Having drink with a friend now and then is not the same as what he is doing and he can't blame your actions for how he is. My ex AH did this. I would go out 4 times a year and have wine with the meal and he'd accuse me of being drunk and make out I was the same as him. I'm not. I don't drink everyday but I refuses to let him stop me having fun with my friends now and then and if we want a drink we are having one. His problem is his problem. Not mine. My son has diabetes but we still eat normal food around him.
