It’s great when women support each other, even if they’re strangers. In this story, one woman left a secret letter for her ex’s new girlfriend, giving her a warning based on her own time with him. The new girlfriend was surprised and posted about it on Reddit, where many people gave her support. This small act shows how a simple gesture can mean a lot to people online.

The woman shared her story in a Reddit post. She wrote, “My boyfriend, Steve, and I have been together for 2 years and living together for 8 months. While cleaning our apartment, I found a hidden letter in the back of a cabinet. It said…

She continued her story, saying, “After reading the letter, I decided to show it to him to see how he would react. When I gave it to him, he tore it up and told me not to believe it, saying she was just crazy and not trustworthy. I told him that the fact he hadn’t found the letter in the 5 years since their breakup was a big red flag for me. It clearly shows he never cleaned that spot, and he’s been slacking on cleaning even more since I moved in.

He insisted that this was just his ex trying to mess with him and ruin his life again, and that I was letting her win. We argued about it, and eventually, I decided to leave and stay at a friend’s house.
