Mental stress, No sound sleep, frighten.

Hi all, in the year 2013 I got married to a girl through matrimony, she was loving a guy b4 marriage and since he got married & due to pressure from family she got married to me. Even after her marriage she was in contact with her ex boy friend which she admitted later on. 1) after few months she started being violent, she used to yell loudly and quarrel as if I am hitting her 2) she used to catch hold of my collar at home or if I walk out to avoid violent then she use to pull my shirt and say u can't go and yell 3) her father has abused me in my office to get her marriage gold when I was just a day late 4) she used to say I m not a man as i was not able to erect my penis due to mental torture. She used to force me to have sex when I was mentally disturb. She used to laugh when I couldn't satisfy her, I am separated with her from last 2 years and moved to different state but I am not able to come out of the torture I faced. I can't get a sound sleep.it's still comes in my dreams etc
