Dear all, After marriage wife (pregnant) Left matrimonial home for Parental home for two days but it more than a year she dint came back. i tried many times to bring her back but she tells to talk to her father and her father refuse to send her back. i called her family also to meet and talk but they abused me and my family. Now two months back wife loged police complaint in my area. Police called me and taken my statement. Police found that m not guilty and told me to approach counselling dept of police. So i have given written letter to counselling dept. Now wife again lodged police complaint in her area. There also police given clean chit to me and asked my wife to stay with me seperately.
