Physical & mental harassment by my wife.

Hi, i am a victim of physical & mental harassment by my wife. Me & my wife are married since 10 years. We dont have kids yet. We have gone under lot of infertility treatments. My wife is from rural area (Village). I work in a IT Firm. Where i have rotating shifts. She has issue with my night shifts. She mentally tortures me if i have to go for night shift. Lot of times she says that you (including my parents) not done anything for my treatment. She abuses me & my parents a lot. She has also hitted me lot of times. I have Pics of the same. Once she hit me on my head & it was injured badly. My Parents are not aware about abuse. Sometimes she behaves so nicely that i thinks that is she the same person. She always tells me that i will commit suicide & will leave a note with your name. I tried explaining her lot of times. But she doesn't understand. I have to manage my personal & professional life. But whenever i am in office i am thinking that if she does anything. Because of which i am unable to concentrate on anything. I am feeling Depressed. I want suggestion.
