Seeking, sadly I agree with the others, it's a land mind. The message shows he see's himself as a victim of you and either has no insight to his behaviors or has been able to justify them in his mind. My son goes back and forth with the pity for himself and venom for me. In my situation, because I'm allowing a slight open door incase the time comes when my son goes back to taking medication and stops his self-medication I would respond "I haven't rejected you, just your behaviors." And in my case I know I would be met with a torrent of name calling, character assignation and a host of false accusations of things I did to him. But then he'd have one more written communication to refer to for clarity if he ever pulls his head out of his butt.
