I think AA meetings are enlightening and helpful, but they are NOT a substitute for Al-Anon. I'm sure you would feel welcome at any open AA meeting--discussion or speaker's meetings are the best. Step meetings or Big Book studies are probably much more helpful for alcoholics--the focus of the Steps is much different.
It's not appropriate for anyone who isn't an alcoholic to share at an AA meeting. If you are called on, or they are going around the room, just say "I'll pass" or "I'm here to listen." It's fine to talk to people before or after the meeting, though.
