allfor, you are missing the point...not ALL members may KNOW the backstory. and may be given false hope hearing stuff like a 65% cure rate. many 'anon members arrive scared and trying still to FIX their partners. this was not another member sharing, this was an outside professional.... at the very least this touches on 5 of the first 6 Traditions....
1. Our common welfare should come first; personal progress for the greatest number depends upon unity.
2. For our group purpose there is but one authority - a loving God as he may express himself in our group conscience. Our leaders are but trusted servants; they do not govern.
3. The relatives and friends of addicts, when gathered together for mutual aid, may call themselves a Nar-Anon Family Group, provided that, as a group, they have no other affiliation. The only requirement for membership is that there be a problem of addiction in a relative or friend.
4. Each group should be autonomous, except in matters affecting another group, Nar-Anon or Narcotics Anonymous as a whole.
5. Each Nar-Anon Family Group has but one purpose; to help families and friends of addicts. We do this by practising the twelve Steps, by encouraging and understanding the addict and by welcoming and giving comfort to families and friends of addicts.
6. Nar-Anon Family Groups ought never endorse, finance or lend our name to any outside enterprise, lest problems of money, property and prestige divert us from our primary spiritual aim. Although a separate entity, we should always co-operate with Narcotics Anonymous.
perhaps you haven't spent much time involved in a 12 step recovery group enough to understand the 12 steps, 12 traditions and 12 concepts that are the framework of AA, NA, NarAnon, etc.
