My wife is forcing me for mutual consent divorce !!

Hi, I got married in June 2014. It all went well till 1.5 yrs of marriage but after that my wife behavior started changing. She used to fight with me over small things. She also started to torture me physically and mentally, and abusing me. Many times she had slapped me, even in public on roads she slapped me. I did not want to raise my hand on a girl so I kept patience. But day by day she turned into more agressive and violent. She also stopped to do sex with me. Later I came to know that she was having a affair with her friend. She used to call him 8-10 times in a day and talk around 40-50 min avg each time, even in late night around 1 or 2 AM she had talked to him. I am sure that guy also used to come to our flat when I was not there. Some other boys also used to send her dirty messages and she also reply to them. One day she told me that she is leaving me and my home and she went away. After few days, she called me and said that she wants divorce. Her parents are also supporting her. She and her parents are forcing me for mutual consent divorce. She is threatning me that if I don't give her mutual consent divorce she will drag my family also in court and put charges over me of physical and mentally torture. I love her a lot and don't want to give her divorce and I want to save my marriage. What are the possible ways for me to not to give her divorce. My questions are : Can she send me or my family members to jail ?? There are 2 houses on my father's name, can she claim over these property ?? Can I transfer my case from Pune to Delhi and what are the chances in supreme court for my transfer petition to be accepted, and due to this will the divorce case be affected like any delay or any stay order ?? How long will the contested divorce case be run in Pune ?? I do job in Delhi and I need to travel from delhi to pune for court hearings, can I take a long dates in court because of this ?? Is police case necessary for filing a divorce case in court on the basis of mental cruelty ?? Thanks in Advance
