While handling negative people you can’t be negative. The more you react to a person possessed by anger or hate or jealousy, the more the other person sucks you and get energized, creating hell for you. Your path is to raise your bar of patience and forbearance, and wait for the opportune moment to talk with compassion and love, not expecting a good result, at least you will not create bad karma!  Love only love! It is your Gain!
