About 498a and dvc

I had an 2nd marriage due to my 1st wife expired. After marriage 1m I came to knew she is maintaining her illicit relation with other who is well known to her from past manny years. I tried to convince her.. but failed. I tried in manny ways to fix this but every time it has changed and upgraded the way she is in contact with him. She even managed to bring him to our home when I am out of station. When ever this issue is brought to question, she makes a big mess and attempts suicide and try to write my name. In the same way last June she have done and immediately submitted the court of the evidences of her letters and got an Restraining order against her and applied for divorce after leaving her at her home. The divorce case is going in court. After 3months she filed and false 498A and DVC in her native place without any proof. I have taken any Dowry or Any kind of harassment towards her. All the claims in 498A she have done are completely false. I have manny evidences also and even 3rd party evidences, audio calls against her.
