"Love the alcoholic, hate the disease". My thoughts on this are that you will only be a hypocrite if you stay with him after you stop loving him. It doesn't sound like you are there yet.
The Alanon program is to help you deal with your problems that stem from his alcoholism. There is no stipulation about staying with them, or leaving them. That is ultimately up to each one of us.
On a personal note, I used to think that my ex-A was my best friend too. After a while, I realized that best friends don't treat each other the way he was treating me. We aren't together anymore, but I will always love him in my own way. The bottom line is, he wasn't good for me and he brought me down more than he took me up. I felt "alone" more times in the years that I was still with him than I have ever felt in the years we have been apart.
Peace,
