What should I do about my dad?

Hi. I am a 20 year old woman seeking advice about my father. My father is an old-fashioned man who has always been over protective of my sister and I. I have always completely understood why as a teenager, however, as the years go on, my father is still finding it hard to get over the fact that I am growing up. I know that I could have it worse, however my father is creating some difficulty in my life with some of his rules. For example, he gets angry at me if I stay out at night, gets angry at me for visiting my boyfriend of two years and other things such as putting highlights in my hair. I am also in my third year of university and working, as well as volunteering, so visiting my boyfriend is very difficult. The best way I could spend more time with him is seeing him at night and staying the night there, but this would not fly with my father. The biggest problem is that my dad has anger issues and does not know how to talk things out. I’ve tried to talk to him, but it always turns into him yelling. Is it just me or is my father too strict? How can I get through to him? What are your opinions on my situation?
