Should I forgive my father?

Growing up I had a pretty rough life, my mom left me with my father and vanished when I was four months (but she took my twin sister with her). The worse thing she could have done was left me with that maniac. My dad was really abusive and I can recall moments where he's hit me for nothing at all.

So anyway, I was 13 years old when a friend of my father raped me and I told him and my stepmother (whom I love dearly) and he just blamed me. He called me a slut and told me, an oblivious 13 year old that I led his friend on. I kinda ignored that and regarded it as him hiding his feelings/rage but the night he came home after I told him about the incident he beat me severely with a electrical cord and threatened my stepmother not to go to the police. I was fine though, until I got pregnant. When my stepmother told him he insisted on killing me and blackmailed our family doctor to do an abortion.

He did A LOT more stuff to me afterwards and I just spiraled our of control and lost my mind and was diagnosed with depression and social anxiety at 14.

Now he wants to make up with me and I'm not having it. I just want him as far away from me and my family as possible but I wonder if I should just let go?
