Dear Prudence,
My husband and I are gay. We live in a deeply red state and can’t afford to leave. I am the stay-at-home parent for our 6-month-old son. My sister-in-law is in the process of getting a divorce and had to start a new job after being a stay-at-home mom. She has a 4-year-old daughter, “Lia.” I started watching Lia, and shortly after, she started saying I would do awful things to her like I pinched her or hit her if I changed her clothes or stepped on her toes if I picked her up. She throws tantrums saying that I’m not her dad and am kidnapping her. This has happened in public more than once. Every time it happens, I have an anxiety attack and worry that someone will take it too seriously or too far. This is a gun-friendly place. It has gotten to a point where I can’t run errands while watching Lia. I don’t want to be out in public with her. My sister-in-law refuses to take this seriously and my husband accused me of being paranoid because I wanted to put cameras in our house. Lia continues to do this no matter how much I correct her. I am this close to telling my sister-in-law to find other child care but I think it might blow up my marriage. I feel trapped. Can you help?
