Wow. I feel your pain actually in that my NPD A sister has been going to a therapist for YEARS that does nothing but enable her and her NPD ways. She'd been going to him before finally drinking herself into a coma and on life support a year ago. I used to go to him, too, back in the 90's and he'd do nothing but tell you what you wanted to hear.
Back to the AA issue... could you contact another AA group with your concern on how this chapter is being run? Heck, is there like and AA "headquarters" or something? Maybe they could send over a seasoned veteran to take a look at their shennanigans.
