Love you forever

You ask me how long I'll love you.

Forever isn't good enough,
eternity seems like just a night.
I say I'll love you always,
you say thats not quite right.

How about this.
I will stop loving you :

When roses turn blue,
and violets turn red.

When clouds begin falling,
when you leave my head.

When I stop missing you,
when I run out of tears to cry.
I will love you always,
until the day I die.
