Mental harrasment against husband and his family

Hello I was married 8 years back.that time my husband told me he has no relationships with other girls and also told that he does not drink or eat non veg as we are strict vegetarian brahmins.they have shown me their house which they said will modify later. All things found out to be a lie. I found out he had many relationships and was also involved in drinks n non veg. In the early days of my marriage he even tried many times to change my personality m look like his ex. I was so depressed my husbnd dnt like the real me and want me yo be someone else.He used to talk On phone for hours behind my back. Used to fight with me for going for parties.i have hidden all this grom my parents as i didnt wanted to hurt them. Later i told this to his parents but they suuported their son n told me to leave. they even speak bad about me in society even now. Later i have decided to handle everything myslf because i wanted to save my marriage.in between i have got pregnant with my elder son, during during tht period i had to face a lot of fights and mental trauma.i was also beaten up. But i tolerated everythng coz of society. Many ups n downs during these 8 years.now this year i was pregnant with my second child, even now he fought with me every now n then and have even beaten me.i was on complete bed rest but he didnt care.today i have a two months old daughter, a few days back he called up at night anddemanded 50k from my savings as i am at my parents house. I said i dnt have it right now .but he fought like always and also threatened to leave me n my kids. I am fed up of this now. Beside explaining it many times that plz dont fight infront of our kids.it is not good.he intentionally do it everytume n shout out as loud as he can. He even wakes my son at the mid of night to show him our fight. My babies suffer because of him N now i dnt want my newborn daughter to see all this. M into a lot of mental trauma since these years and even have stopped going out, have no friends, dnt talk much with anyone because i feel abnormal mentally. I just stay indoors all the times and do household works still has to face this much besides being an engineer . Plz suggest what can i do coz i dnt want to live at my parents house as i cant defame them in society, nor can i live with him with such depression and fights.
