SO, you've got some excellent feedback here. My own contribution is that 'accepting me for me' is quack for 'accepting me as a drinker'. She may have undergone a period of sobriety but she's drinking now, and reverting. For many As this is part of the process of recovery, but she might have to crash and burn before she stops drinking altogether.
Everything you've said and done shows you can't accept a relationship with an A, so you've made the right decision.
