<human>: Can you condense the text into three sentences or less?

Together over one year. Ages in title. 

We were hanging out at his place. Made plans to watch a movie. He's playing a video game, says he will be done in a little bit. I say that's fine, play around on my computer for a while. An hour later, ask when he thinks he will finish up, he says "soon." Hour and a half later, still not done his game. I'm pissed off and make new plans, leave. He is annoyed by me being pissed at him for making me hang around for two and a half hours while he wastes my time. Got very irritated when I asked him time frames on the game. 

Am I over reacting or is this a legitimate thing to be peeved over? What should i do next time this happens? It's not the first time it's happened, and it's really getting on my nerves (I've brought up before that it bugs me).
<bot>: boyfriend spent two and a half hours playing video games while I killed time waiting for him. I'm pissed. Am I over reacting? How should I handle this in the future?
