Mental torture by wife and inlaws

Dear Sir, I am a scientist at one of the well-known research institutes in India since 2020. I was engaged in June (at that time I was doing my post Ph.D. studies in Israel) 2016 and married in Dec 2016. Just after one month of our engagement, fights have been started bet us on very silly things such we will not have a baby in 3 years. She used to say she will stay at my home even after marriage if I don't return immediately. But the all matter was solved by my and her parents saying that she is not that mature and sometimes immaturity blame also on my head. Anyway, at her request, I am back in India after marriage and started living with her but since then she will find all silly things and start fighting with my mother. This is really hampering my research work and career. I don't have a father only mom is there. She doesn't clearly state her intention but every day goes with fights. So far 6 in-house meetings have been held to convince her and her parents. All mistakes go to their side but still no improvements. For weeks, she will not do her routine home jobs. Just sit all day, cook for her, and sleeps. At the age of 60, my mother does all routine activities such as my lunch box, washing utensils, clothes, etc. Inlaws also not supporting us. Please suggest what I can do to either make her behave well or in an extreme case a DIVORCE?? Thank you.
