Don't forget that the biggest reason why you're feeling bad is because she's not with you right now...I think your reaction was fine, just don't do anything more to react, and you'll be fine. If she was cool enough to tell you about it, and it was just for a bit, you can't expect any better. She's on SB, in Miami, at a club, and she's not going to have some fun? psssht, right. Just make sure you have your fun when she gets back and you'll feel much better. They love hearing how much you missed them, so don't forget to SAY it.
