Because you're not here

I think it took you going away,
For me to want you to stay
I've come to find that old saying is true,
You don't know what you've got til they leave you
You won't be back soon enough,
The days without you are so tough
Dreaming about you every night,
I can't wait to hold you tight
It hurts to hear a love song,
With you gone it just feels wrong
Looking at pictures hurts more,
Seeing us together before
I think I might shed a tear,
Because you're not here
