Suggest Remedy To Deal With Abnormal Behavior Of Spouse

Hello sir,I am 22 year old girl, an engineering graduate. I was in relationship with a guy for about 5 years. The guy was not bad he has never tried to ditched me, he also loved me truly but the way he used to treat me was not good. He insulted me many times, he used to abuse me, slapped me once. He has never allowed me to live the way i want to. He has tortured me emotionally, mentally and physically. I have done almost everything for him but he has never helped me in my bad times. we have also get physical many times though during those personal moments he used to be very nice but after that he just dnt remember anything. He used to behave as if i am slut. He has never given me any happiness, he used to be with his friends only even his friends also insulted me. We were classmates during our college , i have helped him in everything but he never respected me. Many time i have stopped talking to him but then he used to blackmail me emotionally and bring back to him. But nw m fed up of everything, i want to move on but its very difficult for me. Sometimes i feel guilty for getting intimated with him, i feel like doing suicide many times. I have no one to support me i never share feelings with anyone. Please help me to come out of this trauma. M mentally very disturbed. I want peace.
