Betrayal in relationships occurs when one’s need for self-gratification outweighs a partner's desire for intimacy and emotional and sexual exclusivity. A Reddit post, shared on July 13, 2026, offered a remarkable example of just that. A man told his partner that his elderly colleague was lending him her car during lunch breaks. The girlfriend (u/summersufficient7657) trusted him until a suspicious contact on his phone exposed his secret vacation plans with his mistress. Her post has received 12,000 upvotes online.

The beach bombshell

The couple had been together for six years, but things changed when her boyfriend landed a new job and made some 'new friends' at work. The man did not have his car, so he started using Uber to reach his office. As time passed, he stopped calling his partner during lunch breaks, because apparently, his kind colleagues, including an elderly lady named Sandy, were lending him their cars. The author trusted him and let it slide. But two days before her birthday, her boyfriend asked if she would like to spend the day at the beach — with his female co-worker.

The shocking affair

The author declined, preferring to "spend the weekend alone." But on a hunch, she checked his phone, and his text messages hit her like a thunderbolt. Someone whose name had been saved as Sandy, with an old woman's photo, was actually Jasmin, a 34-year-old woman. "They get lunch together and chill in the car on break. He’s never mentioned any of this to me," the author recalled. Moreover, apart from just lending her car, Jasmin was in a full-fledged romantic relationship with her boyfriend. Their recent texts also revealed their beach vacation plans. 

The messages left the author heartbroken, but instead of confronting her boyfriend, she wanted to leave the place while he was at work. However, the only issue with her quiet exit plan was a storage unit in her name that had mostly her boyfriend's stuff. In an update, the woman revealed that the man unexpectedly began shifting his belongings out, unintentionally helping her with her plan. Moreover, she explained that her boyfriend had been acting unusually affectionate of late, unaware that he had already been exposed.

The author plans to stay mum and completely cut him off once his stuff is gone and she's moved out herself. 

Cheating census

While the story is shocking, statistics suggest that betrayal and cheating are still at an all-time high. According to the American Survey Center, about six in ten young women (57%) say that infidelity is quite common among committed relationships among Americans. Similarly, YouGov surveyed Americans by asking them 10 hypothetical questions about cheating in relationships, and 33% in a monogamous relationship admitted to cheating, either physically, sexually, emotionally, or all. Moreover, 59% of Americans who admitted to cheating said they cheated with only one person. That said, four in five Americans, including 83% of women who were cheated on, said they were relieved and happy that they found out about the cheating.

Readers empathized with the person with soulful GIFs and helpful insights on the situation. u/Kailsbabydady remarked, “Congratulations, you are free.” uConstant_cultural said, “The best way for you is just leaving without drama; he was heartless too.” u/Wiseness1037 commented, “He wanted you to see his texts. Seems like he was trying to hurt you. An honorable man would have told you. So glad you are getting out. Mourn the loss of what you thought you had with him and then make a new life.”
