Comments: We were staying in joint family after marraige on 17-11-2002 my wife left home twice (In one year) and came back and when she went to her parent's house for delivery of baby on 21-02-2004 she did'nt returned back pressuring me to stay seperate with here, finally b'coz of child i accepted to stay seperate and she came on 14-08-2007 and always use to quarrel with me unneccesary and broke my brothers engagement by telling negative things to my brothers inlaws about my family and had quarrel with me again left house on 15-11-2008 with her mother & Till date she is over there. I tried evrything from my side even staying seperate from my family but still she always follow her mother,brother & sister and harrass me and my family.
I'm feedup with this and does'nt want to continue relation with her nor want to give her any maintanance as I tried my best to keep relation good.
Can I marry without divorcing her, has already earlier also she was with her family for more then 3-1/2 years and again now almost a year.
Please let me know the best way to get out of this with giving any maintanace to her and re-settle my life with new partner
