I need to know that I'm making the right choice?

I've been with the same guy now for ten years. I am only 24 so he has been my only boyfriend. I cheated once when I was 18 only because I had never been with anyone else and was curious. I am at an age where I want to hang out with my girlfriends and go to bars n dance n have fun. My boyfriend will not allow this to happen, I cannot go anywhere without his approval, he uses the fact that I have nothing to hurt me. I recently graduated from nursing school so j have not had a job since early 09 I have no money vehicle nothing! I do not love him but I am petrified to leave for fear or no one else ever wanting me. He tells me I'm fat n ugly lazy n a pig. I'm really not but am only now realizing this. I feel in my heart once I get a job n a vehicle I need to leave, because I can feel myself slipping into a depression and I don't like it. I am worried about what will happen to him and that's another reason I stay. All bills are in his name so he would be strapped financially n also have no where to live. Is it wrong that I want out or should I stay n be miserable so he won't drown?
