She recognized her friend’s cheating boyfriend at a club when he flirted with her — then she set the perfect phone-number trap that exposed him
Friends step in to protect each other from being hurt. A woman recalled a night at a club when she unexpectedly came face to face with her friend’s boyfriend, a man she recognized from photos she had seen before. When he approached her and began flirting, he had no idea who she was or how she was connected to his girlfriend. The story was shared on Reddit on November 29, 2025, by a user who goes by u/RelationshipNice5976. Instead of confronting him directly, she chose a different path, setting up a subtle phone-number trap that later helped expose his pattern of cheating in a way no one expected.
Gave my friend's boyfriend HER phone # when he hit on me at a club

According to her post, this happened years ago, “before everyone had a cell phone.” That night, she decided she would expose him by giving him his own girlfriend’s number instead of hers. She had seen many pictures of her friend’s boyfriend and felt almost certain it was him when she noticed him at the club. “When he introduced himself and the name matched, then I was certain it was him,” she wrote in the post. Although she had never met him before, she already had doubts about his loyalty, which made her plan feel justified. "I knew he cheated on her. She caught him once, and she forgave him."
When he began flirting confidently, she chose to play along instead of confronting him. She gave him a fake name and pretended to enjoy the attention. As the conversation continued, he eventually asked for her phone number. That was when she followed through with her plan. “I took a napkin (that’s how we did it in the old days) and wrote my fake name and his real girlfriend’s phone number,” she shared. She handed it to him casually, unsure if he would notice the number or simply forget about it.
Later that same night, he made the call. “I guess he was tipsy because he didn’t recognize the phone number,” she explained. When the phone rang, it was his actual girlfriend who answered. He asked for “Jill,” the false name given at the club, unknowingly exposing himself. The girlfriend later told her about the strange call, confused about why her boyfriend was asking for another woman. The friend admitted she did not confess right away and chose to stay silent at that moment.
Looking back, she described him as “extremely handsome and tall,” which may have made it easier for him to approach women confidently. Still, she believed he had a pattern of flirting behind his girlfriend’s back. “Thank goodness he called,” she wrote, relieved that the truth came out clearly. She felt that if he had not dialed the number, he might have behaved well for a while and avoided suspicion. Instead, his own decision revealed everything, and her friend soon ended the relationship. Months later, her friend’s life took a positive turn. She met someone new, a man she described as “the most amazing,” and eventually married him.
