Divorce

I got married on 2nd August 2017. My husband works as manager in bank of Baroda. they cheated us telling the false age of him( actual age gap is 10 years but they given us false date of birth which is of age gap 7 years. ) we have document proof for this. After marriage myself and my husband moved to Chennai because of his work location whereas my in-laws stayed in their native. While moving to Chennai I brought my jewels along with me which my parents gave me at the time of marriage . After few days my in-laws along with my husband started mental harassment asking me for the jewels telling that I should keep all my jewels in my in-laws house. Even though i am pregnant my husband continues to harass me calling on names using vulgar words(recordings available). He even bet me during my 8th month of pregnancy when I said No for keeping my jewels in my in-laws house. I became a victim of physical and mental harassment. Fed up with my husband I gave complaint in police station. FIR also filed. Now in this case what is the punishment he gets if I show the proofs what I have? If he opted no for jail then what punishment he gets? Iam taking care of our child(son). He works as manager in bank of Baroda and I am working as software engineer in private sector. What I will get under maintainance/ bharanam? Please help me in this.
