Divorce

Dear attorney, I got married 2 years ago. My in laws told us that she has some fear in mind and is on medications for that. At the time of marriage she was working in a school as school health nurse. After our marriage she gradually told me regarding her disease that she is schizophrenic and on medications from 10 years. During the initial months she didn't show much symptoms but used to remain moody. I thought maybe she had difficulty in adjusting to our place. But when I confronted her family they told me she's suffering from schizophrenia and the doctor has told she shouldn't get pregnant for 3 years in the first place. By that time she was already pregnant.its been 1year since we had a child but she refuses to live with me. I hardly convinced her twice to be with me at my home and brought her and my child home. But both time she left within 1 week that she can't stay with me. We have not lived together for nearly 16 months except for 15 odd days. Can I get a divorce from her and conditions in my favour? P.S - I don't have her doctor's prescriptions
