My husband left me years ago when his mistress became pregnant. I raised our two children alone, rebuilding a life from nothing. Last week, he suddenly appeared at my door with his daughter—the child he had with her—and asked me to babysit. I refused. My heart pounded as he leaned closer and said, “If you don’t help me, you’ll regret it for the rest of your life.” Then he stormed off, calling me a heartless, cruel witch. Two months passed, and I tried to convince myself it was over—that he had said those words out of anger, out of desperation, out of whatever twisted version of guilt he carried.
