Him canceling on me?

Okay, so I’ve been talking to this guy for a while now and we’ve talked about him coming over tonight cause I’m alone for the week. He wasn’t sure if he could make it since tomorrow morning he’s got an exam. So long story short he ended up canceling “the date” tonight because of the exam and asked if he could come tomorrow night? I know I probably shouldn’t be mad about it but I kinda am and I don’t know if I should be cool with it and leave it for tomorrow...Thoughts?
