I recently married under family pressure but i love my girlfriend which is my true love, we both cannot live without each other. My family and my wife knows about our relationship. Now I don't understand how fo leave my wife and start to live with my girl, I don't want to stay at my home all i am planning to run away from my home and start to live seperatly then after sometimes can i file divorce? I didn't made any sexual relation with my wife but i was sexually acting while i was in relationships with my girlfriend for five years but after I marry I didn't make any sexual relationship with any of the girl. Please suggest me what hurdles come here or i can stuck in any legal/police case? Another reason to leaving my wife is i dont feel love for her i dont feel attractive to her. She is government servent but i have a private job. Please clear all my doubts. Main thing after run away from home can I stuck in poilce case or legal issue? Can my wife file a case on me? Am I doing anything wrong? Can their family members hit me? Second how can i file divorce after run away from home without meeting my family n wife
