OT...sort of...I have personal knowledge of this sort of thing. I have a step-daughter, 19, and Husband whose relationship was alot like Casey and Cindy, imo. When we first got together, it was almost unbearable, I almost left. It has taken 4 years, and I'm a counselor, to break through! He would never believe she did anything wrong, unless he saw it with his own eyes, literally! And it was bad, theft of money, items, lying...she, too, I believe is a pathological liar. BUT...he sees it now. He realized that he was doing her no favors, by buying into the bull, it only re-enforced the behavior, that was the angle I pursued. Hey, it was working for her! It isn't now, thank God! Not to say, she doesn't still lie, she does. But it's alot easier for me, when I know he's not being bamboozled, and there are consequences, there is then hope.
