This song is very powerful to me.
First of all, I loved the movie, secondly I am going through the same thing right now. With relationships and it's just too much to tell. The way they tried to understand it was: Just getting out of a relationship, or really liking/loving someone, that may or may not like you back, and you want to fine someone to love you. But you are going through all of these other guys and you don't know if they like you back, and you don't know if it's the right person for you.
