interim maintenance

Respected jury members, Sir ihad married a girl on last year and got separated after 3days of marriage bcoz as she was caught having affair with her cousin and decided to commit suicide with him and not having interest on me. All these conversation was recorded in my mobile automatically. I find this conversation on 4th day and i send her home in the presence of village elders. Than i complained in PS about her suicide and filed for annulment in family court the 8th day of incident.Three mediations failed and i am not agree to accept her. After 8 months she filed for interim maintenance, 498A, DVC against me nd my parents. Sir i have few questions:- 1. She was just passed 10th class and i am govt employe earning rs. 32000 pm and to hand i am getting rs 25000 pm. How much maintenance shall court impose on me. Sir i have few evidences regarding the case.They are call recordings in my mobile with his boy frnd, data includes clear audio of conversation, mobile no of her boy frnd, date,time and duration of the call. Transaction form of rs.90000 transfered before marriage to her father as asked me for financial support. Audio recordings of her and her relatives using abusing and vulgar languages on me and my family in which she was shouting that she was not interested on me and becoz of my insist she married me. 2. Shall my marriage annuled based on above mentioned evidences. 3. What will be the result for 498A and DVC cases based on above mentioned evidences. As she was only with me for 3 days and marriage between us not consummed.we dont have any physical relationship with her as she accepted in mediation. I have also honeymoon resort ticktes and flight tickets planned on 7 th day after my marriage. But we didnt went as the incident happened the 4th day of marriage. Please give your valuable suggestions. THANKING YOU
