Ok i know i probably sound like a wierdo asking this but whats Team Switzerland?

When Bella say she is on team "Switzerland" she just means that she is neutral like that country. She isn't going to choose Jacob's side o Edward's side because they're both very important to her

If you're team Switzerland it means that tu don't care that Jacob is a werewolf o that Edward is a vampire. tu amor them both and don't care what they are and just want them to get along. I presonaly am team Edward all the way so... :P!!!<3(hope this helps)

It means that Bella is neutral- she's not going to pick sides in the Jacob and Edward fight over her.
