Financial, physical and psychological harrassment by Husband

Hi Team, I have been married for past 9 years and have a son who is 8 years old now. Soon after the marriage my husband started financially taking advantage of my salary by controlling my debit card and jewelries. He has too much of financial committments in the form of loans for which he doesnot provide an answer at all. Whenever i stressed and asked about his financial matters he verbally abuses and then beats me up to shut me. His mother is always in his favor. He also drinks very often which is should not question and if i question he again abuses me mentally and physically. He always forced me to give part of my salary to his account for the whole 9 years and am not sure what is he doing with the money. He is also earning well but not spend anything for family. Atlast he forcefully threw me out of his house by beating me when i stopped giving my salary from past 1 month. Now my son and me are staying in my parent's home. Please advise me how to proceed in this regard...please help...
