Should I get help or leave him ?

I am twenty years old . I got married at nineteen . I knew my husband since I was seventeen and I do and did love him but we constantly fight . He is muslim and asked me to convert so I did . Our marriage was good but we fight constantly and argue . Sometimes he grabs me and always he yells but when he grabs me he leaves bruises on me or shaking and pushing me . He is never like that unless angry . Sometimes it gets to the point where I ask him to leave me alone and he wont so I push or hit him aways or he wants sex when we fight and it hurts . We fight over anything and everything . I moved to his home country also . I am not in USA anymore . I had internal bleeding due to a tubal pregnancy and that is when he pushed and hurt me more . Then when the fighting is done everything is normal again .. what can I do ?
