Is my best friend going to turn into my enemy? I'm confused please help! :(?

Ok i understand where your coming from. In middle school everything is different. We all get new friends so we might act different to other friends. Just wait and see a little longer of how she acts towards you. If she still stays mean and snobby you might not want to be friends with her. REAL BFFS will always be there for you and not treat you any differently than they have in the past. Its your decision and all but if she acts like you don't even existed i don't think that friend ship will last. Ask other friends who have experienced this for advice so they can help you. Your bff is just acting this way to show off or trying to fit in. I hope this helps you out. :)
