Domestic violence

I get married before 8 months with traditional Hindu rituals. It was an arrange marriage. After marriage, we started life happily up to one months. In the second months of marriage, she started quarreling with me. After two months, she left my house and went out. For last six months, we (me and my family) are unable to contact her by any mode of communication. Aftre collecting the set of information, we knew that she is staying in Haridwar Shanti Kunj and she is complete dedicated to spiritual life. His family members are not taking too much interest on this issue. once, before six months, she called to my mother that "i will not come to your house and i want divorce". We are completely puzzled and don't know what to do ? and we are unable to understand what actually happened?. neither she or her family is willing to talk with us. How to resolve this issue? Is she or her family is waiting for some time limit to raise dowry or domestic violence case? Is she got married to get money from my job ? We used to call her father and ask the status, he used to reply that she is not talking to us and completely uncontrolled......We don't even know her address and his father is not taking us to her location. Is she can file a case of dowry and domestic violation for the two months of togetherness. please help.
