The addict is putting conditions on you for his recovery?
Clearly there is an argument for personal privacy but I think that would sound like "could you please not discuss the details of my recovery with others" and not a demand that you not talk to this or that person.
That said, when I first started up in alanon it was suggested to me that I not go into the gory details w/ friends and family because after a while thats all that would end up being talked about- and I definitely appreciate that point now. Might be a good time to see to your own recovery- I've discovered a lot of my own issues while doing so- not that I caused RAW to drink but I sure added to her levels of stress, anger, and frustration.
