Am I selfish

So my boyfriend played football for another school, I made it to all of his games, banquets and everything. I drop everything to hangout with him when he’s able to hangout. I go to a smaller school and just cheer for basketball. All I asked him two weeks in advanced is that he goes to my last first game. He couldn’t make it. He had to work. Even though he told me the day of the game he would try to make it, he had work. And wasn’t able to let me know he wasn’t going to be able to make it even. So am I selfish for being angry?
