Input: About 10 minutes go, I sent an ex-friend a decent length DM over Reddit that was very much hateful. This was because he used me and friends as his own ego charger and sent us all a doc titled, "I Used You All" which was him coming out and saying he used us all for his ego, he then blocked and unfriended my best friend, who was on the verge of tears because of how awful it felt to be used and the other friend cried because of all the memories he had with this guy I mentioned. The "using" went on for almost a year.
After I sent the message, I started thinking that maybe it was wrong of me to send that message because it was a lot of hate and started feeling a little bad and had second thoughts about deleting it. So, am I the asshole here?
