Do I have the right to be mad at my boyfriend?

well, since we're only hearing your side of the story id say break up with him. If he still likes you he may ask what he did wrong or that he wants another chance. then just bring up what youve said here, tell him that if he doesnt make it up to you then he's not worth your time. in any case, your waaay to young to be worrying about having a relationship, your prince charming will come eventually, just be patient.
