How to deal with a nutcase boss!?

Okay I have a boss who is not the best boss in the world. He does have some amazing qualties but also he has some very bad qualilties and me and him seem to always clash. I believe its cause he is very aggressive and I am passive agressive. I am a realist I call things out the way they are, cause what right is right and whats wrong is wrong. This has nothing to do with be negative or positive its about being real and real talk! So this is the deal I have been working at this place shy of one year. I have noticed my contemperies who were hired with me or after me get better treatment and get semi rockstar schedules and sections to work at the restuarant. I had addressed the situation with my boss over 5 months ago and we set up a plan for me to be on par with what he wanted. When I meet expectations and went over he did tell me I was doing an amazing steller job but still does not want me in good sections he likes me in easier sections. When he asked me how I felt I basically said " there is nothing I can do at this point for you to realize how I feel or what can change" he did feel very bad about the situation and he said sorry and agreed that I will get 2 rockstar stations a week and also 3 middle stations., and he kept his word and it lasted about 4 weeks and after that it went away. I have asked him over the last 12 weeks if things were gonna change and basically they havent. He wont give me off for a wedding at work and I was the first one to ask for the day off, and its my close friend but he gave it off to the three girls at work who just recentlty asked him and I asked him months ago. He always yells at me and he has gone out of the way to insult me on the internet then block me on facebook, and in the begining it really hurt my feelings but at this point I does not really matter. He always says I am doing an amazing job and I am always giving him amazing results but why does he treat me this way. He loves to yell at me infront of people. He gets mad when people talk to me, he has told people not to associate with me. He told my friend he doesnt want me going to the wedding and thier is no real reason for me to go to the wedding he wants me to work that day. Does this man hate me or just like bullying me and what should I do? Thank You and yes I am a male.
