Am I in the wrong?

At the time I started dating my bf he was living in another state and doing well for himself financially. It was a mutual agreement that he move here with me. When he first got here he had a difficult time finding a job. I supported the both of us from 05/06-11/06 with a little money coming in on his end. I never put any pressure on him while he was looking. Because of our previous situation, I cont'd handling all the bills (which btw leaves $25 a month in my account) and his checks were for saving and misc. things like groceries or take out and a nest egg. We haven't managed to save anything. Everytime we do he wants to buy something. Rather than pay off the overdraft we had to use on my acct while he wasn't working he wants to buy a TV. He drives my car & he uses my cell. I just asked him to split the bills with me 50/50 and that didn't go over too big. A friend offered us an new apt and we would save $600 a month but he won't hear it. Am I being the jerk... or him?
