For provoding food to me and my doughter, she is telling she is not servant for both, last 6 years i am taking hotel food. She is frequently beating my daughter, she never behaves lovable mother to our daughter. Last 7 years there is no marrital relation between us. I tried my best to living with her she never cooperate with me and she is not dutiful wife to me. So I filed a divorce pettion to family court 2 years back. Family councelling held and not settled, then mediation also held for around 1 year not settled. She told me that she wilk not leave me. During mediation, case reffered to psychatist unofficially because of her nature, after dianose they told she has mental problem but no certificate was given because case reffered by mediator. She will not give me divorce, my own house also she occupied, i am paying Rs.12,000 for every month as maintenance. Presently, i am living in rented room. Because of hotel food I have health problem also. I realised husband-wife relation is so lovable relation and Life is also one time, I dont want to waste my life.
