He never went for any job . My parents gave 7 lakhs , 107 sov jewels & a car. When i came out, i drove the car leaving my jewels at home. When i gave a complaint , my parents in law asked 2 months time. In the mean time, my husband repented his bad acitivites & live a good life but on 20.1.14 he stabbed me in knife & ran away. My neighbours caught him & handed him to police. After a year, 5.12.2014, he closed the case. Now I have reopened it. Due to fright , I didn't go for divorce.
