Should i leave him, or should i stay?

I have been married for two years now and been with him for a total of five... in the time i have spent with him he has told me what profession i can or can not go into, who i can and can not hang out with, and what i can or can not do... he threatens divorce whenever he gets pissed and he is always so quick to tell me to get out, some of the things he calls me or says to me have really hurt me and i dont know if i can get over it, he wants me to go to work and be able to support him one day, keep the house spotless all on my own, and have dinner ready whenever he's home... he recently took a job where he works 5 hours away and i only see him on the weekend and talk to him once a day, and is in the midst of trying to get deployed... it feels like he's always trying to leave me and im lonley and most of the time i just wish he wouldnt come home... he doesnt show me hardly any affection anymore so i dont enjoy sexual relations with him, when he comes home all he wants is sex and money so he makes me feel like a piece of meat and a pay check... On the other hand he has always provided for me and hes a good guy, i have never lived on my own and im worried i wont be able to support myself on my salary and im terrified of being alone... and i dont know how to go about leaving, where i should go or what to do, or if i should even do anything... am i just being nieve and selfish... should/ could i leave or wld that be stupid??? Please help.
