Legal Solution required on Matrimonial Issue. Girl harrassing me.

To Legal Experts This is regarding Matrimonial issue. My name is Mr.Ahmed. M.K, basically from Bangalore city & working in Qatar from past 6+ years. About 1.5 years ago I got married to a Girl from Dharwad who was a divorcee. This is Second Marriage & Earlier she was married to a guy from Dharwad & working in USA in year 2012. I got this girl contact through Online Shaadi.com & then we spoken & our family members met. Then we got married about 1.5 years ago. After marriage I had immediately taken her with me to Qatar & both staying together. In 1.5 year both had visited India twice for few occasions. Now from past 3 to 4 months she is back with me in Qatar. From the day she came back, she is starting unnecessary quarrels with me. Unwanted picking fights, disturbing my sleep, threatening that she will go out of house. Every 7 days she starts up the fights. Even she hides my office phone, car keys when I wanted to go to office. She even closes the main door with key. At night she start up fights which I never thought about. During fights she keeps telling about the previous marriage Guy. She makes me frustrated & I had also went for heart checkup because of her attitude. There is no reasons for the fights which she creates with me. How can I handle it if it is continuously happening every weekend. Even I must work & then in home there is no healthy environment. My head keeps aching because of her taunts & torture. She start screaming loudly even though I have not touch her. Seeing this now I’m getting very scared of this girl. Immediately I make calls to my family in bangalore & also her family in Dharwad. Both family try to console her, and asks her why she is doing this kind of problems. She says she doesn’t want to stay with me & wanted to go back. Her parents tell me Not to sent her back. Phone conversations are recorded Now, I am getting scared to keep her with me in Qatar. I told her if you want to go tell your parents and go. I cannot stay with this kind of Girl anymore. Everydays torture making me upset & I had chest pain & went to hospital & had health checkup aswell. I cannot take this anymore & told my family in Bangalore. This is going for about 3 to 4 months now. She can go back to her parents house by her own will. She keeps torturing and keeps taunting with some bad language, which is not good on part of women. She wanted to go back, and even I don’t want to stay with her. My health is worsen because of her. Anytime she might go now back to India. Now, I feel she might go to India & register complaint against me, which is false complaint. Even in her previous marriage she & her parents threaten the same way to that Guy & his parents. Even now she might do the same. Usually we can see they file 498 & domestic violence cases or other cases against husband’s. Even if the Girl is wrong they file by showing pity-ness. I am afraid she will do it and wanted Legal Solution where I can safeguard myself in Qatar & my family
