(Newser) – If you think divorce is a tragic way to end an 18-day marriage, how about divorce as an end to a 77-year marriage? An Italian couple—he 99, she 96—are calling it quits after the husband discovered that his wife had an affair ... in the 1940s. The Telegraph reports that just before Christmas, "Antonio C" stumbled upon letters in a drawer that "Rosa C" wrote to her lover. She admitted to the affair, but her pleas that he reconsider apparently fell on deaf ears. The two, who have five kids, a dozen grandchildren, and one great-grandchild, are set to become the world's oldest divorcees.
