Ok, I know if it's any way like my situation then you cant really just get new friends. When your around friend b and she starts to get full of herself, make a little comment that will embarrass her like "Jeez, put down the mirror princess or stop bragging. But say it in a way like your just annoyed with her, but in still a friendly way. Like your "joking". She will be embarrassed and your friends will notice. Start inviting friend a if you still like her alone without friend b. If she asks why say something like this is a NO BRAGGING ZONE. Make it clear to your friends you think she is annoying but still be friends with them just not her. And as for the boy, go walk home with both of them if you can, or ask him to walk home with you first!
