On Reddit’s r/relationship_advice forum, one man shared the heartbreaking story of how his upcoming marriage fell apart.
He explained that he and his fiancée, Sarah, had welcomed a daughter about a year before their wedding date. But behind the scenes, there was a devastating secret. When Sarah first learned she was pregnant, she confided in a friend that the baby might not be her fiancé’s—because she had been with another man.
As the wedding approached, one of Sarah’s friends privately approached the groom-to-be, telling him outright that he wasn’t the child’s biological father and recounting what Sarah had told her. At first, he refused to believe it. Everything the friend said clashed with the Sarah he had known for five years—someone he believed to be faithful, honest, and loving.
Still, he couldn’t ignore the doubt. He confronted Sarah and arranged a paternity test. The results confirmed his worst fear: he was not the father.
Shattered, he turned to Reddit for advice. After reading nearly every response, he decided to take a second test, hoping against hope for a different outcome. The result was the same.
When he confronted Sarah again, the conversation became emotional and erratic. She expressed confusion, offered apologies, accused him of not trusting her, and claimed uncertainty about paternity. Then, in a stunning admission, she revealed she had cheated on him with three other men.
By that point, he felt numb rather than angry. He called off the wedding and informed both his parents and Sarah’s parents. Both sets of parents were shocked, though her family approached the situation with surprising understanding.
Ultimately, he decided to step away from the little girl he had been raising, reasoning that she was too young to remember him and that maintaining the relationship would only make moving forward harder. He consulted a lawyer, who advised finding the child’s biological father. The friend who had told him the truth knew two of the three men Sarah had been involved with.
He ended his post by thanking everyone who had offered him advice, acknowledging the painful reality but also the support he had found from strangers online.
