My dad is forcing me to live with him.😢

I'm 21 and my dad is extremely over protective. He doesn't want me drinking, having a boy ly friend, and for a long time up until about a few months back he would never let me sleep out on the weekends. Now I've gone behind his back and I've had a boyfriend for a year now and I've been drunk numerous times. I mean I'm 21 why the hell not. I'm not a bad person either, I go to college, I have straight A's and I always put school first. But yet he still treats me like I'm shit. Today he made a comment that I can't do anything right and it really hurt me because he's almost 40 years old and is still living in his mom's house. I'm only still living with him because he literally forces me to. When I was 19 I tried to move out and move into a friends and my dad punched me in my face repeatedly and slapped me and threw me around. I fought back but since then I haven't tried to move out because I'm scared to. I didn't press charges either because I'm scared I'll lose the rest of my family especially my grandma and she's done so much for me. But I just can't do it anymore. I don't know what to do. He always says that if I try to leave I can't take any of my things with me. That I'll leave here with nothing. But almost everything I have was given to me by my aunt and friends and 2 of my pets I got from a friend and I take care of without anyone's help. I just want to leave but I'm scared to and I don't know what to do. I'm just not happy. My boyfriend has asked me numerous times to move in with him but I keep telling him it's impossible for me to leave because of my dad. I want to move in with him so bad but I'm so scared that my dad will go after me and that I'll lose my family.
