There is a freinds and family forum that would be worth a visit. A lot of people there have experienced just what you are going through.
It seems that it is a good thing for the partners of an alcoholic to get help for themselves.
Recovery of an alcoholic can be an uncertain thing. It may take time, there may be failures, he may go further down. It is best not to expect too much. Even when it is going well, he may have his priorities mixed up for a while. Patience and understanding is what is required.
If you have a read of the "to Wives" chapter in the AA book, you would find some useful ideas.
All the best.
