What are the domestic violence limits?can i apply it in my case?

Hi Sir/Madam, I am an working women staying in bangalore currently. I was actually from the small town Anaparthy, Andhra Pradesh. My marriage was done during the 2011 feb. I am happy with the my husband but not with the in laws behaviour. As whenever i will go to my in laws place, my mother in law will torture me in one or the other words like i won't wear good dresses or jewellery to show it to the other people. She and my father in law didn't even bother how much her son's earnings and asks us to send money for the homa which i cannot bear at this moment. If my husband didn't respond for money my father in law calls me and scolds me and my family for not giving money. My Mother in law whenever she calls through over phone she will have the intention to hurt me and scolds me and my family in filthy language. And from the first i don't have a habit to talk in mobile phones every day either with my parents or in laws. For that also my mother in law misunderstanding everything in a negative way and visualizing herself that i don't want to talk with her. even though me and my family tries to explain them they wont understand anything positively from my side and my family side. I am earning more than my husband at my home. neither me nor my parents have asked them about that anytime in the 6 years also nor even went for the fight to their home. But these people if make gold necklace with my savings if my mother in law doesn't like it she will come for scoldings along with my father in law. Hence i reduced going to hometown in order to reduce these issues. i ignored all these because of my husband as he is a very good person and genuine and soft person. But yet he will be silent for all these things which their parents behaviour and he tells me to adjust. Currently i am 5 month pregnant. Still my father in law will ask money for homam/pooja on my name to get good child which is good. I said i will give the money in 3 installments.But he didn't listen and have talken filthy language without a thought i am a pregnant. Now in a week i am leaving to my hometown. If they will come for the fight against me and my family which worries me more during this period. How does i take it forward this one. please suggest. Can i apply a case against my in laws if they will revert in negative way next time. Regards, Anusha
