Non-ADD Spouse with ADD spouse with BPD (but denies it) seeks support group

It's been a while since I was here.  I am ABSOLUTELY convinced my ADD spouse has Borderline Personality Disorder.  I am emotionally detached (out of self protection) from my wife because of her BPD.  I wish it were easier to just walk away from the marriage.

I just saw a post from Dr. Hallowell re ADD spouses with other disorders.  It was posted about a year ago, suggested that someone like me seek "support groups" but listed none.

Is anyone else like me out there who has suggestions?  I love my wife but I'm not a masochist.
