Am I selfish & materialistic ?

We were in class and the teacher started talking about Valentines Day, it resulted in saying how he never gets me anything and how people have nice things and I don't have anything because he doesn't get me anything. He hasn't bought me anything in a year, last Christmas. Since then he's had Christmas, My birthday and now Valentines Day he always expect something from me. He always ask for stuff when we go in the stores and I get it. But turns around today and says I NEVER GET HIM ANYTHING. I've even bought him some damn Reeboks, literally the most expensive shoes in the store. He gets mad when I say " I'm use to it, I always buy my own stuff" I hate it. It gets embarrassing, I mean I don't mind buying my own stuff but sometimes it would be nice if I didn't have to! He could atleast save up or something! He even lied one time and said he got my something from my birthday and didn't, just so I would buy him something. When I say he literally hasn't bought me anything in a year, not even a drink. But oh he can pay $35 for a movie ticket to see Kanye West, and invites me to go and says I have to pay for my own, he's a dumb fuck. This is the message he sent me. Then he calls me a bitch , oh ok, BITCH YO MAMA 
How am I even materialistic? TF I'm far from that shit. He got me fucked up. I'm always trying to help his slow ass out but I can't even get appreciated. POS
