What I was going through? How a law can protect a woman undergoes this situation at husband house?

I am 31 year old woman from Kerala. Mine was a covid time marriage done on sept 2020. I married to the place where in mother in law, father in law, 1st sister in law and her daughter stays. I got bad experience on my wedding day itself. 1st sister in law got car breakdown that day and when I asked what happened actually. She replied ‘Shani’- (bad time) is captured. Felt really sad on my wedding day itself. She kept on making me discomfort in the kitchen first. she asked me to stop singing. she spoke things with double meaning mostly. After a certain point of time she and her daughter and later mother in law completely stopped talking to me and my husband as well. We both have reached from that situation to another that, her husband mentioned the ownership of the house that I stay. 1st sister in law doesn’t do any kitchen work. I used to help mother in law for cooking works before my office starts. Everything happened during lockdown time and ignorance of them happened inside the same house and same wall. Me and my husband left the house once her husband mentioned about property and 1st sister in law spoke to my husband about the money she spent for his UG education even though it is a government college. Felt really bad of it. Mother in law and sister in law didn’t ask us not to leave the house. Only father in law felt sad. We discussed all the bad situation which we faced before we leave infront of 2nd sister in law and her husband too. No body took any action and couldn’t help. Once the ignorance pattern made very bad to us by 1st sister in law and mother in law together, we felt we are nobody and not at all the part of that house, we both shifted the space somewhere next to native place. Few of other members asked us to go back to Bangalore. we couldn’t make it due to financial and lockdown and covid scare situation. Tried lived in the new space like nobody and by not telling anybody about what we were going through. I am unlucky to be in the house where I stayed after marriage and recently I came to know the fact from neighbors that ’I didn’t stayed at that house after marriage’. I got shocked 😳 of this cooked up thing. I was doing work from home and I hardly go out in day time and mostly I go out after office hours, mostly in the night, that’s the truth. I don’t know who cooked up this story. I don’t know what actually me and my husband were gone through. One thing I know I threw out from the house. And kept control on me, because I remember one day I made sudden plan for a one day trip, my mom got call from 2nd sister in law that I didn’t inform her and go. So many stories like this I was going through. Due to the stress I couldn’t concentrate on my job and I resigned my job 3 times during this time. Also ended up in health issues. currently we are in Bangalore trying for new job with my husband’s help. what I was going through? How a law can protect a woman who undergoes this kind of situation at husband’s house. Reply please.
