Hillary Duff made a song called "So Yesterday" and inspired girls everywhere. Here are the signs that your current boo or your ex is so yesterday!

1. He doesn't put in the effort 

EFFORT. IS. KEY!!!

2. He doesn't seem to be motivated 

Did you really grow up picturing Mr. Right to be LAZY? NO!!! Motivation is hot!

3. He's immature 

Does he act like a respectful man or does he play passive-aggressive games with you? Just because he's 20 years old doesn't mean that he will act like it.

4. He's already your ex 

Is he your ex? Is he playing games and messing with your head? He seems like a boy that doesn't know how to grow up and be a decent human.
