I am no expert but I'll give this a shot. Your title reads can someone be addicted to AA? While reading your information I believe you mean to say my husband is negleting the family and is possibly overdoing AA or using it as an excuse to neglect us. Am I close or correct here? I like your "goal to live at home" or otherwise you cannot continue to live like that. I don't think you're being unreasonable. I do think being concerned with whether he is addicted to AA isn't getting to the heart of the matter and may even confuse the issue. I would suggest putting that on the back burner, for now.
I feel your pain. Keep posting, and I'm sure others will be along, too.
