How to be a better man than my father? How van I have a better relationship than my parents?

He has no emotions at all, only anger and because of that I had to become a much more angry person and a jerk to protect myself from him. He is not violent but he's either very removed or angry. He is cheap, he never bought my mother anything. He has no ambition at all. He has no friends or social life. He never really said anything to me unless he was telling me what to do or yelling at me. My parents fought constantly and hated each other. I really like this girl at college who is really nice and really upbeat most of the time but I am too afraid to ever ask a girl out or become involved with a woman long term because I fear I am just like my father. If you've ever seen the movie Sideways I fear I will become Paul Giamatti's character, alone living in a small apartment a failed writer with only one friend and a crappy car. How can I change now at 19 years old?
