What is up with girls?

I understand, we're all different

               I'm a girl, I just don't understand somethings. Such as how cruel other girls can be. I have a friend, whom I've been friends with for years! But recently she's been going through a lot.

               Her so called friends are making her chose between them and someone else. The thing is if you were her friend she wouldn't have to chose, get that through your head! Understand, that if she chooses neither, you pushed her to that choice

              My friend, let's give her the name Jackie. Jackie's been my friend since 4th grade. Now, going into five years. She's never been so tore apart than with these friends. See here's the thing, true friends don't have each other choose.

             It's like having her choose between BTS and All Time Low and if she choose BTS I couldn't be here friend anymore. It's just not fair!  No one should ever choose between people, ever. If they are told to it may be a mentally abusive relationship. Help them, please!
