Divorce from Wife

I am married for 5 months. it was an arranged marriage. I was not willing for the wedding. My marriage is not yet consummated as I don't feel attracted to my wife. My wife is torturing me emotionally and mentally to get intimate with her but I cant do it forcefully. She is also mentally torturing my aging parents. She is always threatening me to have sex with her or else she will leave the house or commit suicide. On the night before 12th August on my birthday, she planned a surprise at night, but as I was down with fever, I didn't want any trouble and wanted to sleep, I was rude to her and i said i will celebrate next day morning. Next day morning without informing me or my parents she called her father and left the house in spite of my mother and me begging her not to do so. Now she wants to return but I and my family do not want her back. me and my family we feel mentally tortured by her behavior. I know i might have been wrong, but please advise me 1.if I can get a divorce? 2. Do i have to pay her alimony if we settle for mutual divorce? she is a graduate housewife 3. What kind of allegations can she bring against me and my family and can I prove myself not guilty.? please suggest. Reagrds and thanks in advance.
