Dear Annie: I’m confused about an issue that involves my husband. We have been separated for 13 years. We try to work things out all the time, but now, suddenly, he said I cheated on him. He also said that all I do is lie to him. He said he doesn’t want to listen to me when I tell him the truth. He listens to everybody else. So, should I keep trying, or should I just get the divorce and move on…
