I used to feel a little sorry for the guy. I know emotional abuse is terrible, and can do pretty horrible things to your mental state. It can lead you to do things that turn into bigger messes that you later regret. And if you find your support in online communities, by all means talk about your experience online.
But there's a difference between airing your feelings, and writing a 10k word manifesto complete with private chatlogs and posting it to every space you can to "get word out." Especially when your words are incendiary to one person in particular, identifying them outright and pointing a big fat finger at them.
And then after the fire is blazing, claims that if given the option,
he would do it all over again.
He's since lost all sympathy I could possibly muster.
