Father is controlling!

So about 4 months ago I got out of a relationship I was in for almost 2 years. My very first relationship. I'm 20 years old and list my virginity to this guy. We ended because my family is too controlling and because I still live with my father he doesn't think I should be dating so he never met my ex. Which took a toll on our relationship. My father is so controlling that when I tried to move in with my ex to get out if this house my dad went crazy and starting hitting me. I stayed because he threatened my friends and stuff. My dad also does not allow me to have a job. AGAIN IM 20! Legally an adult. I have to go behind my dad's back to do anything! Especially when I was with my ex. Now I'm dating a new guy. We've been together about 2 months and so far he is very understanding about my dad, but so was my ex. I'm afraid that my boyfriend will eventually give up and leave me because of this, just like my ex did. To top it off I might be pregnant with my boyfriends child. I'm not sure yet, so don't get all you're being dumb on me. I use protection and birth control it's just I missed a period. But can anyone give me some advice on what I should do about my dad and my new relationship? My boyfriend wants me to move in to get away from my controlling dad. Should I? P.s my dad says if I ever leave he'll put out a missings persons report? Is there a way to make sure he can't do that?
