@fairy as someone who was also neglected as a child, I'd like to say I don't think it gives you the green card to be mean towards others. He is an adult now, he should be able to cope in a different way and regulate his emotions correctly. His trauma is no excuse for his abusiveness. As I said before I was also neglected, but never have I ever was jerk towards people because of it. As much as I resent my parents I was never disrespectful to them because I can also see their side of the story. But hey maybe that's just me🤷♀️
