Well, it seems that he does a lot to help out in the house. Maybe if you start helping him out on some errands he wouldn't be mean to you.

No, he cooks. He doesn't even do that all the time. I make my own food when I have to and have no problems doing do. I never ask him for anything. I'm not going to do favors when he doesn't help me out with anything after he gave me word. I forgot to mention it but there has been a few times where he confronted me on resolving our problems and telling me he would help me out. Selling his car did not help me out. He broke his word.

The fact that he gave you these promises shows that he does care about you. I know that it's disappointing when someone breaks their promise, but he may simply not be able to keep these promises. Also you seem self dependent and you're an adult now. You should try and achieve these things on your on (learn driving and getting a job etc).
