do i need a divorce

Dear Sir, I got married a year and half back, it was an arranged marriage, in the same caste/community and there was no dowry involved. Pre-marriage things were good, I and my parents had the impression that the girl and her family are educated and civilized people, post-marriage however things didn't looked normal to me and there was some sort of tension visible in the girl's family. Later on my wife disclosed that she is not having good terms with her mother as she was tortured and mis-behaved with by her mother, at her home before marriage. Things like these about her mother and her brother were told by her. By no means had these things looked normal and I was totally puzzled. Then one day she told me she had a boy friend before and he gifted her gold chain, I told her whatever is done is done but don't keep any contact with him now. Meanwhile her family started behaving strange with me and she herself started picking up fights for no reason and started calling her parents for intervention when the arguments get heated up. She even misbehaved with my mother, when she came to visit us for a month immediately after marriage. My mother just asked her not to wear string tops and skin tights, was that so wrong that she made such a noise and started shouting and abusing her. I never said anything about her clothes and always respected her freedom to choose and wear the clothes she like, but requested her to wear something more acceptable and comfortable in front of my mother. Things like these started happening frequently and I decided to send my mother back home, thinking she will feel bad and hurt if these things continued, in reaction my mother got angry with me also. Anyhow, even after my mother left things didn't returned to normal, and I have to leave my wife to her home quite a few times, because my in-laws were getting aggressive and I had no means to show them what was happening at my home and who is at fault and my wife was getting hysterical day by day, I told my in-laws about everything even her ex-boy-friend, and asked them to advise their daughter. I don't know if they advised their daughter anything but clearly they started giving me veiled threats. Things got so bad afterwards that one day she ran off to another city without informing anybody, later on I came to know that all this happened with the help of her ex-boyfriend. Meanwhile, when I informed about my wife being missing to my in-laws they didn’t even co-operated with me, also they were indifferent and uncaring. However they would daily call me and ask me about what am I doing to find her, then on one pretext or other they threatened and abused me. Eventually my wife came back after 4-5 days. I accepted her back and not even once did I raised the issue of her leaving home, our life was peaceful for a month and then one evening she picked up a fight for no reason, finally when things got heated up, she threw a diary on me and walked out of the room. Puzzled by what is going on, I opened the diary; I got shocked to read that her stay during the run off was arranged by her ex-boyfriend. I couldn’t bear this lie and discussed the matter with my father-in-law. He came and took her daughter along. Since that day I am living alone and am unsure of what these people actually want. After few months I received a mail on my official email id, the mail contained the user id and password of some email account (containing my wife’s name in the user id) and in the subject line, sender asked me to read the inbox and sent items. I called my wife and asked her - what is this all about? To my query, she responded with a shock and ignorance of any such thing, and she even said she doesn’t have any such email account, I then decided to read out the mails to her, as I did so, I found out that those indeed were her past emails to her ex. When I confronted her with the names of people in the address list and the content of the mails, she broke down and admitted those were her past emails. One shocking thing I found written there was that she and her ex, married each other in a temple and the guy tied a gold chain around her neck. Also afterwards he sent her court marriage papers, which she signed and sent back to him. These and other intimate things were written in the conversations. Now she is saying that this was not a marriage as there is no witness and the court marriage didn’t happened as the guy never submitted the papers in the court, I am really at loss here and don’t know my marriage status and don’t know what to do now, I am thinking of a peaceful divorce by mutual consent, but she is not ready for this either, she is not coming back and neither she is giving me divorce, also now it has become difficult for me to accept her back into the relationship. I am feeling tortured everyday and nobody is helping me in this matter. When these facts were presented to my in-laws and their relatives, they dismissed them as false and asked me to go to court rather. I don’t know what to do; I wished a simple life and am faced with complex and manipulative people. I don’t know what kind of trap these people are setting for me. I want to know if I need to take divorce from he, because she was already married earlier. If yes, are those e-mails credible proof, admissible in court of law? Also she has not filed any case against me till now, but if I file for divorce then I fear she may file false dowry and domestic violence cases against me, I am unsure of their intentions and feel unable to continue in this relationship. On my lawyer’s advice I have obtained anticipatory bail for myself, but what will happen to my family members, if they (wife and her parents) file false cases against them, because anticipatory bail is not available in their state of residence. I want to get out of this problem and want to save my family as well. Kindly help me, I have heard that these kind of cases, end up in harassment, torture and money extortion. I am a well educated person with a good job, but still I don’t have this kind of money to give to these terrorists and neither do I feel the cases will be good for my career.
