How can I kick an ex-boyfriends ? am I self centered?

Me and my boyfriend just broke up recently because according to him, he cannot take my being a "career woman" anymore. He said I am more devoted to my friends, studies, organizations and work than to him. I am a 3rd year college student and modesty aside, I am a deans Lister and I have to maintain it until I graduate so I really do my best to study well. In addition, I am the current president of the theater arts club of our university so I have to stay with my members and practice school and we usually finish so late because of some preparations and meetings. Another thing is that I work. I am teaching during Saturdays to out-of-school youth, out-of-school adults and out-of-school children and then on sunday, of course I go to m and then go to bible studies and other mission works. Plus I am managing one of our family business. my boyfriend knows all these before I said yes to him. I explained everything to him and he said he understand and he would help me. but then he keeps on demanding for a date even though it is already late and I am tired. He's being jealous with my work and told me to let my sister handle it but I can't because she is already handling one of my family business. not just that, he is jealous of my friend and organization. He wanted me to quit being the president and he wanted me to stop hanging out with my friends when in fact he knows that my friends are helping me in my works and obligations. and then one day he told me just stop being in the deans lister because according to him it sucks. He told me that I cannot use a DL title in finding work. He is even jealous with my cousin who is a guy who is always with me. He always want to call me even in the middle of cl, meetings or important occasions. and when i did not take his call, he will eventually get mad at me and say bad things against me. he even humiliated me in public and embarred me at school. At first I thought I love him so I just did my best to understand him. So even if I am really tired I have no choice but to go out with him even if it is so late at night. But then last week, he punched my gay friend and told him to stop dating with me. He even shouted that I am not a virgin because according to him something happened to us when actually none. I am 100% virgin I swear. I am so pissed off so I broke up with him and he told me that I am being selfish and self centered. He is spreading that I am a worthless and useless woman who just uses a guy who is inlove with me to gain popularity and that I am a gold digger when in fact I did not even ask anything for him...I did not ask even a piece of candy...gosh...I am really annoyed with this guy and I don't know already what to do...
