My wife committed suicide

My wife committed suite after one year of our marriage just for simple reason that me & parents went out to Hyderabad for our tenants function. Before booking tickets I asked her does she want to come with us she refused hence I booked tickets for me & my parents. She is a fits patient takes 6 tablets everyday while committing suicide she ate her entire month tablets at a time. In hospital doctor said now there is no chance for her in future to become pregnant in future.She sleeps at 11:00pm in night & wakes up at 9:00 am does not involve in any activity she is just like a furniture in house full day watching TV. My mother only takes care of house. My parents asked me to go alone and stay then she might change and involve in house activity; when I asked her to come for separate rented house her parents refused and said she is a fits patient and want somebody care full day. I asked them my mother cant cook for her all the time if required I will come and stay with you in your house and pay monthly rent in your house. Even for that they are not ready her mother informed let her become pregnant then later we will think on it.She is 33 years old & I am 37 years old I dont think there is any chance for her to become pregnant now. As she is a very lazy girl even I dont want to adopt a child and spoil his life.Every month she will suddenly go to her parents house anytime at-least for 10 days in a month as per her wish.Even when guest come to our house she want take care of them. When I informed this to her parents they reply why should she take care of them guest are not her friends let your mother look after them.My father is only worried he asks me to be quite till her parents die; after that only she want have any option and will know your worth and change.
