Sept-
you asked him the question that you need to have answered "would it make any difference to him if you told him . . .etc"
It seems it did make some difference in that it gave him his carte blanche (in his mind) to act out even more. This is a childs mind in a grown body that has the resources to do the harm of an adult. He cant be corrected w/o throwing a tantrum so you have to act on that understanding to protect yourself. I hope you are able to keep safe physically and emotionally from this because it IS abuse childish rage coming from an adult. I really dont know your situation but this is what I feel I can validate here.
