My Girlfriend’s Best Friend

She treats both of us like utter garbage, yet my girlfriend bows down and kisses her toes on a daily basis. She is a robot to her. A puppet to the highest extent. Her best friend has belittled her for fifteen years and yet my girlfriend obeys her and idolizes her every move. She has had three divorces and currently has two boyfriends at the same time. Her son is suicidal. That should tell people something.
