Jenny forgot her phone was sharing her location during a trip. She said she was with family, but her map blipped to a beach resort at night. She claimed to have just slept - surprise! She’d prettied up and spent time with a guy she’d secretly been chatting with. Oh, and they’d celebrated 20 years together with kids. Jenny’s now paying her own bills and living solo. Guess independence looks different these days.

When he asked, she claimed she didn’t like Adam - but the real question was: “Are you sleeping with him?” Yep, that answer said it all. Sometimes your gut’s just right.

    His girlfriend and her friend were so late to pick him up, he got suspicious and decided to hide in the parking lot, watching. They pulled up, but instead of saying hey, they went straight to making out in the car. He had to tap on the window to get their attention. He was so numb he just told her to never contact him again. Ouch, but hey - real love and wedding bells came later!

    The stats game is tricky, too. Everyone defines cheating a little differently (like, some think kissing counts, others don’t), so the numbers can get fuzzy. But no matter how you slice it, seems like cheating hasn’t exploded recently - it’s just the internet’s favorite drama.
