“Sophie,” she said. “I think she’s his ex.”

That night, I demanded Mark meet me. He arrived with roses, tears, and a story he clearly thought would soften the blow. Sophie had come back into his life, he said. Old feelings had resurfaced. He “needed time to think.” So he invented the rat infestation, sent me and the kids away, and tried to live a double life while he decided which woman he wanted.
