Not Ready To Fall

When I look into your eyes
I see all that I need
Because everything you are
Is everything to me.
And when I feel like letting go
I hang on alittle tighter
Because I know that you'll be there
To catch me when I fall.
But then I think about the day
That you won't be there for me anymore.
And my heart shatters
I fall, I'm tore.
Then that day comes
And I let go of you
I'm not willing too
But it`s something I just have to do
Why do people always let go
Before your ready to fall?
