Yes, go to Al Anon.
As for feeling like you're the only adult and parent in the home; that's what many/most/all spouses of alcoholics feel like. When a father sitting next to me in Al Anon said that he felt like the only parent in the home and that his AW was like an extra child, the other Al anon spouses completely agreed, many of them cried as the emotions of being a "single parent in a married home" came through. You probably have been a single parent...long before your wife began going to AA.
