My five-year-old daughter, Lily, hasn’t seen her dad in almost a year. Mark lived a few blocks away with the woman he left us for, a distance that felt like a thousand miles of silence. After the affair, he ghosted us. No calls. No child support. Nothing. Still, Lily asked every night, “When’s Daddy coming back?” It crushed me. I had to learn to be her mother, her father, and her protector all at once, while my own heart was still in pieces.
