I'm reminded of a story I hear on NPR about a woman who kept having checks that we sent to her disappear. Her live-in boyfriend helped her by giving her support and helped her try to figure out what was going on. She finally caught him in the act - and then he told her that he had a mental health condition and that he was getting help... She tried for a while to make it work - they even started planning a wedding - but eventually they broke up.
