Take care. You are doing, in my opinion, the right things, especially Alanon. If you haven't already, spend some time reading the stickies above.
Also, there are many posts on this board from people who married alcoholics when they already knew they were alcoholics, some of whom also had children with them. Please read many of these posts before marrying this man. They will show you your possible futures.
Lastly, Alanon saved my life. It did not work nearly as fast as I wanted it to, as everybody has different experiences with it, but it worked. I think if you keep going you will find it helping you.
My thoughts are with you.
