Can I get divorce on suppressing medical facts like Chronic Asthma and her mother's mental illness?

We were married on 2/12/2019. After 15 days I saw Asthma pump in her purse then I asked her abut that but she said it is used for dust allergy nothing else. Then after 5 months I came to know that her mother is mentally retarded since 25 years and I found some symptoms of mental in my wife also i.e Unsounded mind, Unable to sleep overnight, always confused state of mind, Batheing at midnight (1.40 am) ect.. Then I went to Psychiatrist with her while doctor observing her she was completely submissives to the treatment. After that she went to her father's house in July 2020 and now a days she lived in her office quarter without prior intimation to me and my family.. I and my relatives asked her father about divorce because of hiding these medical illness but they denies our proposal. So now, 1)How can I get divorce from her? 2) Can I lodge police complaint against her and her family members for deliberately suppressing marital/Medical Fact and it leads to cheating?? Or any other solution for me??
