I have thought about taking my AD to an open meeting (when she wasnt in the middle of a binge) and sober, just so she can see how damaging an alcoholic's behavior is to friends and family, and also so that she can see that she is not the only person out there with this problem and that lots of other people and families are also going through similar experiences.
If its an open meeting you can both go and if you dont feel comfortable speaking with your alcoholic there, dont. But you should most definitely go to one alone too.
