His baby...

My baby is gone again
he left me by myself to face the night,
I could tell by the look in his eyes
my baby wants to be with his baby tonight.
She is the one that he desires
and it is she who holds the key to his heart,
my baby is with his baby tonight
as my world begins to fall apart.
I can see it in his face
there is no lying in his new smile,
still he tries his best not to hurt me
by saying he'll be back in a while.
But i know for a fact
he'll sleep in her arms through out the night,
he has no intention on coming back
until the sun is shinning bright.
How could i be so sure an certain
of a fact i cannot see?
I know my baby has a baby,
I know cause that baby
used to be me...
