My husband beats me everyday for no reason & to have sexual intercourse without my consent, swearing

I'm married since past 7 years. After a month of marriage my husband beaten me up very cruelly. Everyday torture, having sexual intercourse without my consent, swearing on me & my parents in front of anyone, everyday beating me, hitting, pushing, shoving, punching, biting, kicking, slapping, hair pulling, kicking on female genitals, raping me, etc. is everyday routine of him from the one month after the date of marriage till today's date. I now have son of 2 years, my husband also damaging my relationship with my son, and abusing my son in front of me to make me agree in his lifestyle. In today's date still he beats me very cruelly by slapping, kicking, biting, shoving, pushing, hitting, hair pulling, swearing on me. He tortures me in almost any manner which includes Mental, Physical and Verbal Harassment. In this of the past years since marriage I had gone 4 times to my parents house and asking them to giving me shelter and not to send me again to my husband, they every time only say that, "they can't help me out" and sends me again to my husband by blackmailing that they will commit suicide if I can't go back to my husband. Now I'm so depressed, he doesn't allow me to meet my friends, can't make me go outside home, every time harassing me by name calling of anyone, checking my phone everyday. He even doesn't allow my son to come to me, which feels so depressed and harassing. I want divorce and I asked him for divorce, but he tells me that, "He will kill Me but won't give me divorce". Now I can't be able to handle this everyday torture & belabour from him. He is not agree for mutual consent divorce. What can I do in this situation. I can no longer stay with that person anymore. I have thoughts of suicide everyday. Please help me out.
