After marriage i started new job even though my husband was against it.Some misunderstanding started between us slowly and most of the adjustments were done by me to avoid fights.After 2 years we were blessed with a baby boy and i had to reluctantly and was also forced to quit job to take care of our kid.And i agreed and things went smoothly again for 3 more years.I got busy with my motherhood. I felt my husband was happy and was changing for the happy family. But i was wrong, he had a physical relationship with his ex college friend. They used to have sex in hotels. They even had sex chats and used to share nude pictures . This broke my heart completely and was disturbed mentally. I wanted to enquire my husband with all the proofs in my hand.without the proof he would prove me mentally retarded women. Initially he asaulted and abused me for blaming on him.But when he knew abt the proofs, he accepted and apologised for his mistake and begged me not to take divorce only for the sake of our son.Even i dropped the idea of divorce thinking the future of our son.Later few months he acted as if he changed himself completely but he always had disrespect on me and my parents. I even suffered domestic violence once which shattered me into pieces. Even then he apologised me and forced me to drop the idea of divorce. I again started to adjust and compromise with my life only because of my kid and his good future as all elders advice. This adjustments continued for few more months.But once i saw his ex girlfriend calls and daughter pics in his mobile, i was again mentally disturbed and after thinking many times, i made up my mind and left him without explanning him . I packed all my luggage and came to my parents with my kid. Now i got a job in which i opted work from home so that i can concentrate on my kid and support myself financially. Am trying to move on but my true love towards him is making it difficult. Please advice me on this Anu mam. The step which i took is right ? After seperation he is harassing me to visit son and kidnapped him 2 times. I really don't want to share my son with him.Please advice what should I do.
