Return the Artist, Song and Lyrics.  Arnold Schwarzenegger and Maria Shriver may have this song in their heads right now:

You love her
But she loves him
And he loves somebody else
You just can’t win
And so it goes
Till the day you die
This thing they call love
It’s gonna ____ ___ ___

Here is Yesterday’s:  “I Still Haven’t Found What I’m Looking For” by U2 :

I have climbed highest mountain
I have run through the fields
Only to be with you
Only to be with you

I have run
I have crawled
I have scaled these city walls
These city walls
Only to be with you

But I Still Haven’t Found What I’m Looking For
