Domestic violence

Sir It’s been almost 1 1/2 years since I got married. Before marriage my husband lied to me and my family about his education that he is a graduate in Hotel management ( I myself being a post graduate). And he promised me that he has no problem from me studying after marriage for IAS infact he would send me for coaching but after marriage I realized that everything he said was fake and the environment was totally different there. Everything they are in habit of using abusive language and they used it for me and my family too. They stopped my studies. Started suppressing me and mentally pressuring me on changing myself. I am by nature an introvert (and I have told this thing to my husband before marriage) but they everyday would shout on me and scold me to attend their parties, be a part of their cheap conversations and sit beside males while they were drunk. My husband would shout and break the things in front of me to scare me. I went into depression and came back to my house when I was 6 months pregnant. But my in laws would call me and give me tension instead of knowing that stress tiggers a severe pain in my stomach. I would have lost the baby but fortunately he was successful born. Now I am pursuing LLB from my paternal home and I went to my in laws two times but they say that won’t let me study so I came back . And also my husband is having extra marital affairs. They have sent me court’s notice to come back but I can’t as I am not safe there and they would stop my studies. Sir please suggest me on what grounds can I file a case against them and also how can I get the custody of my baby as I am afaid they would take him ( baby is just 8 months old). And I also want to know if mental torture also comes under domestic violence. Regards Pranjul Singh
