Dear Carolyn: Until last year, our daughter, 34, and her 32-year-old sister were as close as could be. We all live nearby.
About two years ago, tension became obvious between the older sister and her brother-in-law, including nearly physical confrontation. He accuses her of lashing out because she has lost control of her sister, and she accuses him of being mentally and emotionally abusive to his wife. She says mutual friends and family have questioned whether her sister is “safe.”
