Can't take anymore!

So I'm an idiot. I got divorced last spring, moved to a different state and rushed in to a relationship because I was scared. Moved in with him street only 3 weeks. We've been together almost a year and everything is awful about the relationship. He's controlling, manipulative and emotionally abusive. I'm slowly planning to leave but it's hard. I don't have money saved up to move. My sister has offered me her spare room but last time I lived with her it resulted in a big falling out. I don't have money saved to go straight in to my own apartment. Worst part is his aunt cosigned my car and I'm afraid she's going to try and take it. I just tried to refi in just my name but my credit still isn't good enough. I feel sick at the thought of having to go home.

The problem with the car is my name is the primary she's the cosigner sho she'd let it go back and it would throughly fuck my credit that I've worked really hard to fix. I'm not going to stay over the car. I just need to figure that part of the equation out. I work 2 jobs. I can't be without transportation.
