One man reportedly spotted a woman cheating on her boyfriend, so he decided to reveal her infidelity! According to Metro, the guy wrote a quick note to the seemingly unaware guy about his pregnant girlfriend’s alleged actions. Apparently, the guy who wrote the letter was sitting behind the couple at the Detroit Lions’ game on Thanksgiving Day.

That’s reportedly how he saw the “inappropriate text message conversation” between the woman and another guy. Sadly, her oblivious boyfriend was sitting right next to her without a clue. So the man behind them penned a letter to enlighten him. Then he reportedly shared about the encounter via Facebook! Of course, the jaw-dropping letter has since gone viral.

Here’s the details from his Facebook post.

“I was at the Detroit Lions game today when I noticed this woman who looks 8 months pregnant in a seat in front of me texting a man messages like ‘I wish I was with you all day’ and ‘I will see you as soon as I’m done with him,'” wrote the guy in a Facebook post. “She kept hiding her phone every time her partner put his arm around her or reached in to talk to her.”

This is text from the infamous letter he wrote to the guy.

“‘Hey bro, I don’t know you and you don’t know me. When you get home check your girl’s phone. She’s been texting ‘Jason’ saying she wishes she was with him all day!”

A screenshot of the Facebook post was originally shared via Reddit. However, the identity of the man was not revealed. It is also unclear whether the couple is still together or not. FanSided also shared another perspective of the incident. What if the guy was drunk and the entire ordeal was all a mix-up? Unfortunately, no one knows!
