Being ill treated by one's father

My father is a banker. From my childhood onwards he doesn't treat me in a proper way. He talks evil to me and even send dirty videos. Try to touch my private parts. I never told anyone about it.I was afraid my family will be separated and my mother will have to suffer for this and I don't want people to thing bad about my father. Now I am 25 years old and completed my graduation. Allhamdullila Allah introduced me to Islam and I reverted to Islam in 2014. Now I read salaah keep roza and try to be in hijab which brings doubt in my parents' mind and they try to oppose. I don't understand what should I do next. please suggest.
