Not at all
One thing you will notice as you learn more about Alcoholism, the stories are nearly the same!! I used to think we were "differnt than other problem drinkers", then I read your story. I thought back to the first time my AW got "mad enough at me" to go to an AA meeting, she came home and dumped out the 2 bottles of wiskey I had for cooking in the house, but not the 3 bottles of Irish cream I had. Never thought much about it, all she ever drank was beer, untill I found the empty bottles while she was in rehab.
There is a progression to this desaise, slow at first but gains in speed as time goes by. My best suggestion to you would be to state you concerns clearly, not in a demanding way. There truly is nothing you can do to force him into seeking help. And start learning all you can about alcoholism now. The more you know the better you'll be able to support him when he gets ready to seek help. And he will need help you can count on that.
