Iwishonstars,
I think you are asking if there are NA + Nar-Anon meetings in which an addict + their loved one goes to the same meeting?
There are "open" NA and AA meetings which a spouse could attend, likewise with Nar-Anon and Al-Anon.
There is a church near me which hosts a NA meeting in one room and a Nar-Anon meeting in another room at the same time -- this allows couples to travel to a meeting together but, they are each attending a different meeting.
There is a couple who comes to my Nar-Anon home group - he is an addict (20+ years clean), she has a child who is an addict -- he comes as support for her. I call them a couple simply because they always come together - I do not really know their familial status.
