Awww...that's no good. Was this an isolated incident or has stuff like this been happening regularly? Because if if it hasn't happened before, there's always the possibility that she's having some kind of issue that's going on. If it's been happening often, maybe she's pulling away. There's no excuse for not calling you because she was at dinner. I'm sure her family is nice enough to understand that her bf just got out of surgery and she needs to check on him.
Don't rush into making any judgements though...give it a few days and then bring it up. Tell her that it made you kinda sad that she didn't call you. See what she says. If she gets defensive, you may have a problem.
I hope you figure things out either way! Good luck Razr!
