“My fiancé, Arthur Mckay, had just beaten leukemia. A bone marrow transplant saved his life, and we were supposed to be planning our engagement party, celebrating our future. Then she walked in. Diana, the donor's beautiful, fragile ex-girlfriend. Arthur became obsessed, claiming he had "cellular memory" and that the donor's cells were compelling him to protect her. He postponed our wedding plans for her. He let her invade our home, touching my art, sleeping in my robe. He called me possessive and cruel when I protested. The man who once promised to cherish me was gone, replaced by a stranger who used a medical procedure as an excuse for his cruelty. The final straw was my mother's locket, the only thing I had left of her. Diana saw it and decided she wanted it, weeping that her dead boyfriend had owned one just like it. When I refused, Arthur's face hardened. "Don't be a child," he ordered. "Give it to her." He didn't wait for my answer. He strode forward and ripped the chain from my neck, the metal stinging my skin. He fastened my mother's locket around Diana's throat. "This is a punishment, Ella," he said calmly. "Maybe now you'll learn some compassion." As he wrapped a protective arm around her and led her away, I knew the man I loved was truly dead. I picked up my phone, my decision made. "Dad," I said, my voice steady. "I'm coming home."”
