I feel lost..

I'm in a relationship that I feel I have no power or say so in. He decides where we go, when we go to bed, what we eat, when I get out of bed, and even when I shower. I'm in a financial burden and unemployed. He won't let me get a job and even made me leave my jeep with my family when I moved... What should I do? I feel like I need his help and he knows it.. And he's holding that over my head..
