ANSWER:
Such people are only interested in making you react negatively in response to their verbal abuse and humiliation. Once you respond, they become happy for depressing you. You must turn the table on them by NOT Defending yourself to his verbal abuse at all NOT EVEN with a single word.You must not also argue with him over anything at all. Let him talk and talk without a response from you except a big smile on your face. This will kill him slowly but eventually, he will stop because he feels silly and ignored.
