First of all great news on her getting the fibroid taken care of. I hope everything goes well when she does go in for that.
I know how that feels to get worked up and have the evening get pulled out from under you, as I have been there many times myself. Maybe if you let her know how much you were looking forward to last night and how she let you down hurt you. This would communicate the disappoint and your feelings to her vs. just the silent treatment.
I'm working on this myself too. I know there are times when it is better not to say anything but keeping it inside is worse I think.
