Every often she quarl and get herself to her parents house after few months she comes with Unknown persons and her mother to me makes huge drama and aploiges to me and ask me to give an chance to stay, she had been 7 times to her parents house and returned back with huge drama. Now almost a year she had gone to her parents and after staying there for 8 months she had given a domestic violence case in there area Police Station with lot of influence she had maintained whole Police in the station. I went there for introgation by SI who was not at all ready to hear to my words. With forcefully they asked me to take her this time or they will arrest me they said. Due to the police harassment I took her. After that again they are calling me to attend me to court for maintenance case, still now I had not received any notices by court by person or post, they are abusing me over the phone, wife is staying with me now. What should I do? Regards Manjunath
