Domestic Violence and Abuse. I am being constantly threatened

My husband constantly physically, emotionally and mentally Harrasing me. He abused and beaten me in front of driver. He used such a word that a woman would prefer to die instead of listening such abuses. He threatens me. I have not told this to anyone. I can’t take this anymore. I know if I will keep bearing al this one day either I will lost my life and I will become handicapped. I want to come out of this. We work together in the business and he threatens me that I keep doing fraud. He has multiple relationship including one with his distance cousin. He is a womaniser. I feel trapped and helpless. I want to come out of this.
