Wife not ready to stay with husband in husbands' paternal house after retirement?

SIr, I have following questions? 1. I am an 36 yrs old Ex-servicemen retired after 15 years of service on Jul 2021, I got married on Nov 2013. During my service period my wife was staying with me but after my retirement she refused to stay with my parents in my native place. 2. She had a complicated VP shunt surgery on 2016 because of which she can't deliver a child naturally or it could get very critical at the time of delivery. So we have not planned a baby biologically. 3. After retirement I was staying with my wife in a rented flat in her native place preparing for my competitive exams but since I am Bengali and she is Marathi it was getting very difficult for me to manage all the administrative issues that any person gets while staying in some other state in India. Though I understand Marathi but there were so many competitive exams which I couldn't appear in other state so I decided to shift to my native place which is West Bengal, But she is refusing to come with me. 4. My parents are old now( Father retired from Railways age 67 yrs mother home maker age 60 yrs), my younger brother is a banker and posted in other state and staying there with his wife and son. So I have decided to stay with my parents and start my 2nd career in West Bengal. 5. My wife and her mother always mentally harass me that my mother has done some "kala Jadu" on her and that's why she is ill and refused to come in my paternal house. 6. Now when I my telling her I am going to stay in my paternal house she is asking for 'Divorce'. kindly suggest me a possible solution for this problem??
