"...couples need tools to determine up front what's driving their doubt, and whether they still have the will to work on their marriage. Enter something called 'discernment counseling,' the brainchild of William Doherty, a professor of family social science at the University of Minnesota. He hit on the idea after a Minneapolis family-court judge asked him to develop a program to help couples on the verge of divorcing possibly reconcile. The judge had been surprised by how many husbands and wives he encountered in his courtroom appeared to get along well, which got him thinking that divorce might be more preventable than people in the, um, divorce business—judges, lawyers, therapists, and couples themselves—think.
