I think it refers to bad relationship. When one is the dominant while the other is the follower. Sometimes it also about abusive relationship.
Here is a simple way to explain the meaning. When you are in a relationship, you must be imagine it to be super happy. But.. Occasionally you will find someone takes you for granted. They dont respect you for who you are, they use you for their own convinience. Such a person unfortunately do exist. What do you want and what you are doing is not their concern. They want their needs to be fullfilled, as long as they happy… They wont ever be considerate towards you. Because you are suppose to make them happy.
This is my thought. How about yours?
