Ive got some really good friends in NA, the ones that make it seem to delete all the numbers, get a new email, make new friends in NA. So yeah no contact, reminds me of a new guy we had in AA about 2 months ago...came in half pissed and announceed that his sponsor had suggested that he not hang out with old 'friends' and how he wasn't prepared to do that...hope he finds his way back in the future, he hasn't come back since...ok so he's back to drinking a bottle of vodka a day but at least he still has his 'friends'...insanity?!
Concentrate on you, maybe by you going your new path your friend may follow suit in the future...but enabling her isn't going to help her much...hope that helps?!
