I got married on April 2016, on the third day of my marriage, my wife got a message like 'I Love You' on her whatsapp from person who was boyfriend her. We had a fight over our years. Then i quie. then that matter i told her sisters. She did not tell me a few months she is pregnant. She take contraceptive pills. but I do not know. I quite. Then she saw my photo on my mobile with an office girl. She made a lot of violence. My photos are so many with the different girls in the office all is my office friend. she irrrated me on that a few weeks. From marriage day we meet only a 40 days. in a month i go home only 3 to 4 days becouse I have a job in Pune and she is in her father's house due to her job and she is not resigned her job. Yesterday I had gone home then it did not come. And not receive my call. She's family also not respond me and my call. Now she says that I did not want to stay with you. And she needs a divorce. But I want to stay with her because I am in a poor house. And their family is rich. So let me now suggest what I do....
