Am I right or wrong for the decision I have taken?

After I got fed up by his doubting on my character every now and then, I took this leap from staying with him and came to stay with my parents. We had a love marriage 5 months ago with lots of struggle with families,ending up with no support from either side.Few days after he started doubting on me having physical relations with many guys. Gradually it became an everyday crisis and went beyond in getting physically torchered by aggressive hits.He would drink everyday and took control of my personal mails and doubted on every single friend I had in the list.Other times when he is in good mood he would shower me with unimaginable love and I would forget all that happend overnight.He is a cancer by sun sign and I thought its his sign fault that he switches over moods and so eventually I can take control and I started overlooking the negatives.But as a human and a faultless girl I could'nt tolerate the slangs he would say to me and the inhuman manner of hitting me,that my face stay swollen for days and get stiff marks on my body.And I moved back to my parents who after seeing me have strictly said not to return back.It is hard as I loved him so much.We loved each other so much during the initial days and it was never so easy for us to get each other.As I remember those days I feel sorry for my attempts.If I left my job and city for him, he left his sophisticated life and almost his family.Although I can't forget the fierceful face of his at times and so I have decided to stay away from him and have left this relationship upon time.Another 6 months and our marriage can be attempted for divorce for which I am keeping my fingers crossed. Only if he gives respect to my presence in his life and values my love for him in this life.Else have thought to live in his memories the rest of my life while I take care of my parents.Kindly suggest.
