Divorce Compensation & Imprisonment Case

Our marriage is about 10 Years now. We are not feeling comfortable to live with each other. So we thought of divorce. As of now we don't have any children. Basic reason for my divorce as per my wife "She continuously saying that I am having affair with her younger sister. This came between us. So we are fed-up with this continuous argument on daily basis. So mutually decided for divorce. We don't sleep in same room for years Now she saw some normal pics of her sister in my phone. And she keep saying wrong alligation that I am having nude pics of her sister and she left our house. Then also we decided for mutual divorce and division of my current property equally and I agreed. But now she is telling that I will file case on you for Imprisonment for extra marital affair & we took some emergency birth control pills for birth control. So she mentions it too that it's effected wrongly to her health and he includes her claim for heath issues too. And I will see for maximum compensation. She include her sister in case too. We had 2 business together from which one is closed and from 1 it's in huge loss. From which we had few properties. Her sister and we are good friends and her whole family abondend her. It's nothing like affair or something bad between us. So there is nothing to prove as there no physical relationship involved. What action she can take and how much compensation I have to give. My financial condition is not so good. I don't understand what to do. My wife is 40 & I am 35 I run that loss business for years and no profit till now. Please ? help
