Moving far away from abusive husband??

So I have been with my husband for about 3 years since about the first year he has been super abussive and controlling. I feel so trapped. I feel like any moment I'm just waiting for him to get mad and hit me or go crazy yelling. And he has threatened to really hurt me if I even leave him. I want to move out of state and get away from him but at the same time I feel like it's not possible. He made me quit my job so I'm currently not working. Any advice or has any one been through the same and things turned out okay?? I'm posting anonymously because I'm embarrassed and afraid. 😔
