Should I say something

My boyfriend invited my friends to join us at dave and busters today, about a week ago. It was a sort of birthday celebration even though my birthday was two weeks ago. 30 minutes before the planned time to leave, both the girls cancel. And my boyfriend decides that we choose another day to go. By that time I was upset my friends cancelled but I at least thought me and my boyfriend could go considering I took an hour to get ready (and he knew that). And it was a day we both got off work. Instead I get cancelled in by everyone, even the guy who has nothing else to do today. He did not even offer to still go or to do something else today. I don't know if I should tell him this. Or if I should just leave it all alone and pretend I am not upset about anything.
