Am I being unreasonable?

Alright, today was my birthday. I spent time with my friends for a bit, not too long...anyways for my best friend's birthday I took her out the whole day. I bought her lunch, already gave her gift, and got her a few other things as well. For my birthday, she got me yogurt, said she owed me a gift, and made other plans to see a movie even though she knew ahead of time my birthday was on this day. I wanted to have dinner with her and another friend of mine, but the movie was at 7 and that didn't happen. Am I being unreasonable to be mad at her?
