Should I let an “ex’s” fiancée know he’s cheating?

r/

Notable: ex is used loosely here.

I (25F) went out with a guy in college a few times but nothing ever really came to fruition. Really liked him, but he ended up moving and we didn’t speak much after he moved. He started dating someone in late 2022 and was recently engaged within the past year, if Im not mistaken. We are mutuals on Instagram, so I’ve seen his posts over the years. Out of the blue, I received a snapchat from him a few days ago, but it was just a random picture of what seemed to be a hotel lobby/hallway, so I imagine it was a fluke or he sent it to all his contacts. But this morning I received another snapchat and this one really caught me off guard. He openly admitted to cheating on his fiancée of over two years with more than 100 women, followed by how he’s a piece of shit human being and he’s disgusted with himself. Mind you, we have not had any sort of contact since about 2021 at the latest.
I mentioned this to a few close friends, all of whom said the exact same thing: tell the fiancée.
I’m conflicted, as Im not sure why I’ve been trusted with this information, how many other people he’s told, and if it’s any of my business to be informing his fiancée. However, thinking on it, if I were in her shoes, I’d want to know my fiance is telling other women he’s cheating on me.
I’ve not responded to him, and currently have no plan to. What should I do?

    Tell her. She deserves to know the person she’s planning on spending the rest of her life with is a POS

    For God sake, wouldn’t you want to know? tell her. If you have any proof the better but nonetheless tell her.
