I spoke with my counsor last week about my fear of dating another A. He said one of the main things to look for is the importance alcohol holds in a person's life: For an A, alcohol has a special importance - how they talk about it, always have to have it around, bad behaviors while drinking, personality change while drinking, ignoring negative consequences due to drinking (so they can continue to drink). All true for my AH.
I would say listen to your gut.
