I've always hated my "father"

I've always hated my dad.. All my life he's been nothing but awful ! When I was little he would hit me pretty bad and if my mom wouldn't stop him I'd probably end up at the hospital... My mom would just tell me that I couldn't tell or they would take me away. Now that I'm 22 I wish I could take my sisters from them so they don't have to live with him! Even though he doesn't physically abuse them he's still so mean to them . Today he told them they should move out even though they are just 15 & 17 What should I do? I have 2 kids already and we don't have enough money to rent a bigger house 😪 and to make matters worse my mother is pregnant again .....
