DEAR ABBY: A good friend in our prayer circle, "Diane," has a friend, "Suzy," with whom several of us once socialized. We've all distanced ourselves because Suzy has anger and stability issues that have become increasingly frequent since her former spouse has begun dating again. Diane allows Suzy to verbalize all kinds of half-truths and act out with volatile behavior, which some of us feel is basically encouraging destructive mental health.
