What should I do about my boyfriend ditching me on our anniversary?

Hello all,

I'm currently in a very loving long distance relationship. Today was our 6 month anniversary (which had been long anticipated by both my boyfriend and I). However, my boyfriend decided to spend the day with his friend instead of me. It would have been nice to have Skyped or had some kind of call session for the occasion... He told me he was going to hang out with his friend for a "little bit" but it's going on 5 hours that's he's been gone now. What should I do? I feel like if I confront him about it, it'll erupt into another argument. We've fought in the past about how he spends so much time with his friends and I really don't want to bring it up if possible. What would you do in this situation?
