Abby, she is convinced that she’s being followed, but doesn’t know by whom or why. She tells me about terrible arguments she has with her husband because she thinks he orchestrated situations in public places. For instance, she claims he seats himself in a position to look at other women. The poor man is blind in one eye and has limited vision in the other. She also believes his ex-wife flirts with him and he is probably cheating with her, although they have been divorced for 20 years. She resents his contact with his grandkids and his family because of it. I should add that her mother was diagnosed with early-onset Alzheimer’s at around her age. It’s heartbreaking to watch. I have mentioned it numerous times, as well as suggesting she speak to a pastor (she thinks the church may be in on it) or a therapist, but she tends to dodge it. If I try to contact her husband, she will start to think I’m a traitor. I don’t know how to help. Please advise. — TRAINWRECK IN ARIZONA
