I would check out SMART recovery. They have in person meetings in many areas, online meetings just for family, their own forum, and lots of reading materials. They are based more on the scientific side of addiction, and dealing with it in this way. They also are close to al-anon in they don't believe in enabling, they do teach healthy boundaries, but they focus more on communication with loved ones instead of detachment, they encourage treatment, importance of self care and goal setting for yourself, etc.
