A couple on the brink of divorce took their two kids on a Mediterranean cruise, hoping to save their troubled 17-year marriage. Their relationship was toxic, marked by constant fighting and even violence. Both had gotten court orders to stay away from each other. The husband was depressed and had thoughts of hurting himself. He blamed his mom and wife for his problems. The wife wanted out and was possibly seeing someone else. She told a therapist she felt trapped and wanted to leave the kids with her husband. Then, during the cruise, she vanished. Did she die, or did she simply run away for a new start?
