I want to live far from my wife due to her fighting habits

I got marriage in June 1994.We have son 23 yr&daughter 21 yrs.In 2003 my wife started a lot of quarrel due to doubts. She got depression after that police complaints,women cell complaints, stay away from home with valuable documents-cash-jewelry-documents etc.Some time stay away with both children some time one child.Life is going in hell since she got schizophrenia,bipolar disorder and all related problems.Due to my introvert nature,future of our both children or fear to be alone,I could not separate till that date in spite of many times she out me from home which we have purchased in her name from joint saving account.Our son has completed his M-tech and our daughter has completed only 12th.Children could not appose her prperly but they know-it is wrong. Now family members, relatives and friends make the distance.I have lost my patience to stay with her.If I stay alone in rented or self purchased house.What she has right,does she enter forcefully in my house.I can pay for her needs.
