Don't You Want Me

In the song "Don't You Want Me", there is a conflict between the girl and the guy. The two were once in a relationship, but soon broke up. 

The guy feels that the breakup was unfair. He's bitter because he feels the girl used him to get to where she is. He taught he everything she knows, and then broke his heart.
The girl disagrees. She feels she got herself to where she is without the help of the guy. She is unapologetic for the break up because she felt the need to move on without him. 

These differences occur because both the guy and the girl want to be right. Thinking like this make themselves seem better. The guy wants the girl back, so he wants to make it seem that he deserves her, and the girl wants to move on so she wants to make it look like she is better off without him. 

I have experienced a similar situation with my sister. We were arguing about who got to watch TV in the living room. I was there first and had left for five minutes to do something else, and she came to watch her show. When I came back, she didn't want to let me watch my show. I felt I deserved to watch TV because I was there first, but she said that because I left she deserved to watch her show. We argued for a while because we wanted to be right even though we both understood where the other was coming from.
