My wife gave birth to a baby with dark skin. We’re both very fair-skinned. She broke down in tears and insisted the child was mine. I demanded a DNA test—and the results confirmed I was the father. I apologized and begged her to forgive me. She did.

On the day our son turned 18, I received a call from an unknown number. To my absolute shock, a man’s voice said, “It’s time you learned the truth. You’ve been living a lie for 18 years. I’m your son’s biological father.” I was stunned. The man went on to explain that he and my wife had a brief affair while she was away on a work trip nearly two decades ago.
