We've been married for about 3 years. I have lost all faith in my wife and this marriage. There is no physical contact with her. She is waiting for a child and then she has all her plans to harass me and my parents as she knows I am the only son of my parents. She had also defamed me by calling in my office and putting allegations of extra marital affairs on me. She has threatened me for committing suicide and always says that I am torturing her and harassing her.

I have asked for a mutual divorce but she never agrees but now I really don't want to continue with her in any way. She had gone to mahila mandal to file a complaint but she herself was found faulty and was asked for counselling. Now please tell me without my consent can Law force me for a physical relation with my wife? Till now whatever she has done doesn't it come under harassment against me?

What's the best step for me to take now? She wants to come back to me now but I have stopped her, till when can I stop her?
