Boyfriend troubles. help, anyone?

well me and my boyfriend have been dating for almost 5 months now. if that helps anything. but anyways, he usually sees me everyday. well today he went to the steeler game and has barely talked to me today. i understand why he didnt text me at the game but now he has been back for hours. he was able to come out to my house tonight but he decided to go out to his dad's house. and now tomorrow i wont see him all day cause he is going to be with his friend. and the worst of all, he is barely communicating with me. i might get to talk to him through texting every 2 hours. usually he gets back to me pretty fast, but today i feel like im being neglected. how should i approach my boyfriend about this situation?
