Alternate option for divorce to start a new life

Me and my wife got married in Arya Samaj Mandir in july 2014. Her Family was against the marriage.My family supported me. She is from Patna and Iam From Delhi.She came to Marry me from Patna to Delhi.3 months after our marriage her parents got ready to accept our relation but requested to send her back for 3-4 months. They said they want to save their reputation and will get us married in front if everyone in a grand manner. She went back to Patna. 2 years passed but she did not return. Now she has been completely brain washed By her family and she says she dont want to come back. I am not forcing her to return because we cannot force someone to stay with us.I am ready to move on.I want to remarry and start a new life but I know i Cant do that without divorce from her. She dont have any proof of the marriage. But I am scared what will I do if she creates problem after i remarry.Because she is a girl and You know the power Of girls.One statement in enough for them to prove me wrong.she stays in Patna but I dont have her address. She has blocked all my numbers and there is no source to contact her. If I Cant contact her I Cant send her the divorce notice. I want to know what are my options to get rid of this completely without creating problems for future. Apart from divorce are there any other options?
