False allegations of rape by a lady with a subsisting marriage

I had an illegal relation with a married lady for a period of one year. She already knows that I am married with 2 children. Now she trapped me and charged a rape case on me under IPC 376. She produced some photos also in the court. I was arrested on July 30, 2016 and was in Jail for 67 days. Finally I got bail from Bilaspur High Court and the trial is going on in Session court. She had already given his verbal statement in front of Hon Judge and her main point is, I had sexually exploited her under the pretext of marriage and also hiding the fact that I am already married. In fact she knows everything and her main motto was money. She even claimed in the court that after 15 days of getting bail, I again visited her house and we had sexual relations . Please guide me what is the merit of this case and how I can come out with a clean in chit from this false allegations
