[Low Key]

Well, as you said, you two aren't too serious. If you wanted to help move along the relationship, this would be a great opportunity to. If you don't want to, then skipping out would be a great move. There's not that much to it, and that's why everyone thinks you're ready to bolt on this girl.

If you want to talk to her about why you have some apprehension about going, feel free to. It could help bring you two together. But don't do it with the idea that there's no chance you're going. Go in with an open mind and the awareness that she's going thru a lot more than some possible social awkwardness and you'll be okay. Probably. Or she'll think you're a totally selfish prick. It's hard for me to say, as I don't know how she feels about you. She obviously has some feelings for you, or she wouldn't want you there with her, as her emotional support.
