Groups of three friends don't tend to work out anyway, even with the nicest people. Then throw in a toxic person and the friendships often dissolve. But that doesn't have to happen! It's important to let your bff figure out this girl's true colors for herself, and she will! In the mean time only get together with your friend when the mean girl is not around. I know that's hard, but it will give you an opportunity to form new friendships with other people...which you need to do anyway.
