My Best Friend Moved In After Her Divorce—Then I Learned the Sick Truth from Her Ex

My best friend, abandoned by her husband, begged to stay with me. I agreed, and my husband didn’t mind. Two weeks later, her ex showed me proof at the store: texts and photos of her affair with my husband, ongoing for months. I confronted her at home, where she wore my robe, and told her to leave. When my husband returned, I showed him I knew. They both left that night. I changed the locks, rebuilt my life, and learned betrayal often comes from those closest to you.
