My boyfriend blew me off, what should I do?

I made plans two days ago with my boyfriend to go out today, he ends up making plans this morning with his buddy instead and doesn't tell me until right before he leaves. I know he didn't forget because I reminded him this morning. I'm extremely livid right now, and not sure what to say to him or what to do. We just started dating 2 weeks ago...

Thanks everyone for your input, you're right, it does reveal his true colors... This is extremely upsetting, but since it's so early in the relationship, I think it will be a lot easier to move on.
