Captain, I would agree w/you that if she's asking about him being an A, that in and of itself would indicate there are issues.
Is your friendship w/her such that you could direct her here to do some reading and educate herself? Clearly she's going to have to make her own decision, and it seems that if you can find a way for her to learn about alcoholism, what it really is and what she can expect as time passes, it would be a better situation than for you to be directly involved. Or at least that's my best shot at it...
