Married recently I want divorce from my wife

Resp sir I have been married recently about 2-3months my wife kept a false case on myself and my parents on saying that we are expecting extra dowry from her but actually what happened is she use to harrash me in bedroom saying that we get separated from your parents and I used to refuse her that we stay United but days gone during festival we went to her home her whole family members made a pressure on me saying its better to be separated, Later we came to our home and I told my parents that she is harassing me to be separated since many days but I don't want to hurt you by saying that but know even there family made pressure on me but I don't want to be separated from you, by knowing it she called her parents that my parents are scolding there parents then they came immediately and asked everything about it and the matter was over later the next day she without informing us went off from my home to her city and filed a false case on dowry but she actually want to be separated and know my doubts are 1.she made a false dowry case how should I prove that she is lying to the police that instead she wants to be separated. 2.can I go for divorce after the settlement of these case because I don't want to leave with her for rest of my life she and her parents made a newsence about these by saying that my father misbehaved with her and my mother warned her that she will open the gas left and make her die. 3.by seeing all these things if she comes back to my home there is no protection to my parents if she try to make my parents to be drown into false issues can they file a protection case against her if she stay during the divorce proceedings. 4.Is there any duration or months for divorce after getting marriage. 5. She is saying that now she is pregnant is there any chance her to escape from divorce as if I am prepared for my son or daughter who ever they I will take care of them.
