Telling your friend to tell her to say it to her face is kind of contradictory, so I'd say, just go over to her and tell her how you feel and work out whatever you or her have done wrong. What is the fall out over? If you're true best friends, I can promise you that there's no way on earth this will last forever, even if it does last a long time it will never be forever if your friendship is good enough. If not then it'll take time, but you'll grow new friends. But definitely go to say it to her face and talk it over :) Hope you guys will be okay and remember to tell us how it's going
