Comment by Amy stitches everything on Don’t pick up the trash you threw away - Chapter 13

You know the thing about this that hits the most is that he clearly liked and respected her before. This was a relationship where they didn't want to get married, even as friends. 

I just don't know how you can do this to a person you grew up with. It's like he's a completely different person. And after she is the only reason he has anything to come back to.
