Within every love affair,  
there comes a hurting time.  
Sometimes it keeps on hurting  
until the end of time.  
Tears fall on the pillow  
where you once rested your head.  
The evening shadows  
grow longer every day,  
since you left with your new love  
and went far away.  
Now it just keeps on hurting,  
every time someone  
mentions your name.  
It just keeps on hurting  
for I’ll never find  
someone to replace you.
