Do I have a right to be angry at my bf?

He just called me and said that him and 2 of his buddies are coming over....Normally I wouldnt care, but its late and I wannna sleep. Also, we live in a room in a itty bitty townhouse with a roommate. I dont want to have to stay up and be tired with people sitting on my bed til midnight! His response was, I dont get it you have nothing better to do? Um hello sleep! If there was a seperate area to hang out then that would be cool, but Im not in a social mood right now (not to mention PMSing)! AH! Im so mad, should I be? If so, what should I say to him?
