I just found this forum and reading through a lot seems to make sense. I've been listening to this song for the last few days and it seems to sum it up perfectly.
"When I'm of sound mind
I know I can't have you
But that means that half the time
I only think that it's half true"
"Every time my phone rings
Every time something comes in
I pretend, I believe that it's you
It's something that I have to do"
I wonder if nada surf have heard the term limerence before?
