Him flailing his arms around looking through her tweets from 2 years ago was his death throes. After he not just doubled-down but tripled-down on his accusations, that was the cue to let him burn as the drama vultures circle him. Trying to end things on a peaceful resolution after he lashed out at your previous attempt doesn't bring you any positive relations from people that were already against you and his audience still wants your blood. His half-assed apology announcement was very much a "guys, I don't want to get dogpiled anymore, please drop it" tweet.> She apologized to him.
I am so done feeling sorry for this chick.
