Am i excessive??

This girl at my boyfriend's workplace hacked my boyfriend's phone. She uploaded a boomerang of her selfie in his all social media. The caption was "pretty gurl😍". I'm so annoyed and I think it's impolite because there is a social media that containing only important people & family. So i DMed her instagram "Hey, girl. Sorry, it does not funny anymore when you hacked almost all of my bf's social media, especially WA. You know it's kinda privacy. Please, know your place. But since u're ugly, i'll forgive you for now😉".

Oh, and my bf apologized to me, he explains that all the girl said was; she wants to try my bf's new phone camera, he has no idea that she hacked his sosmed.

Am i doing it too much for sending that DM?
