I made plans for my boyfriend’s birthday but he already has plans with his friends. Are my feelings valid?

I told my boyfriend I made plans for him on his actual birthday but he told me he already made plans with his friends. I told him that it’s fine and I’ll reschedule it for the day after. But I’m not gonna lie, I’m disappointed. But I didn’t make a huge deal out of it cause it can be rescheduled. Am I wrong for feeling disappointed? Am I being unreasonable
