I am hindu, got married Apr 17. She got concieved in May 17. She stayed with me only for 2 months in total due to my job. She has been living with her parents. Delivered baby boy in Jan 17. I and my parents were not allowed to come to their house to see the baby Citing we didnt take care of her during her pregnancy. She blocked me everywhere. She has not talked/ visited my parents since marriage. We have been living spearately since more than a year. She wants me to separate from my parents/brother and wants me not to talk to them. To have friends which she allows. She/her parents have asked for a mutual divorce or else they they will file petition for divorce/ maintenance of wife/ child/ custody of child. I dont want to separate. My wife is not willing to come to me. She is from a well settled family and she is their only daughter. Now her parents are saying we will not send their daughter & my son to me. Since marriage she withdrew 10k p.m & post delivery 20k p.m
