Harrasment by husnand, fraud, dowry

I got married 5months before but my husband had suddenly started fighting n shouting on 15th day of marriage at midnight n saying to give a divorce n asked to pack my bags n was saying day he got married but he didn't want to but his family wants as he said. He called his mother n abuses alot n asked for divorce n she says to me dat he is mad n plz don't say all dese things to anybody n blackmails me...after dat time passes his behavior started changing as he has a split personality n inlaws n his sisters say not to say anything to anybody because it will destroy both family image n says u have 3more younger sisters think of them n ur father is ill u r d eldest wat people vl say etc.... I was feeling like I m living in jail or cage. Where I m not allowed to talk to anybody accept the family members not even allowed to go to terrace or stand at balcony of my room or go in park in front of my house... in Dec he beats me while I was sleeping at 2am 9 slaps.. just becoz my family came a day before to say dat not to abuse me n my family... He wants nobody to b in contact with me n says I vl do ds to ur sister or brother whereever they r u can't even find d bodies.. since after 2days of marriage he always to out from 9.30pm to 11.30pm till now n when I asked you he abuses n says I do dat with girls n all dirty things..When he is in room in afternoon he didn't want dat if I m in room, he didn't like me to wear bangles to put lipstick n says I vil make ur life hell neither u can digest nor throw. But in front of relatives or other people he behaves so gud. Nobdy can say dat he is like dat. When I say these thinks to his parents or sisters they say he needs doctor n u can only made him right..as he smokes too much n go outside daily wd friends. N now he is demanding so much rupees in lacs otherwise I vl b torture like ds...Everybody at his home knows his mental condition n his nature but they still get him married as he put very wrong allegation on me n his family also takes his side..
