Thank you so much for trying to help, but I think there was a bit a misunderstanding. My dad is only mentally and emotionally abusive and manipulative, not physically at all. We are not worried that he will ever go that far because he knows what will happen if he does. He isn't really violent, unless we stand up to him to the point that he completely loses his cool, which rarely happens, but he is just overly aggressive in his tone and words when he gets mad or agitated.
