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 অথবা Edward's side because they're both very important to her

If you're team Switzerland it means that আপনি don't care that Jacob is a werewolf অথবা that Edward is a vampire. আপনি প্রণয় 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.
