To get divorce from my sick wife

My wife is a too clean person,she won't eat food prepared by my mother or her mother. Toilet is not shared by her. Always on mobile,sleeps very late at night and waked up at 8 am only,very lazy to prepare food. Doctor said that since her age is 52 it is difficult to treat.No sexual relationship,since 4 years.\nI sold my house and invested in her properties.12 years before.,she doesn't rent out this building and hence I am bankrupt.I have constructed a house too in her property.She had agreed to give some land in my name,but disagrees now.\nWe have a daughter,age 22.
