Is this the end

Is this the end?
Then why does it feel
We'd only just begun
I thought we were done

I think I'll hang on
If you still want me
But if you don't
I guess I'll move on

And if you need me
Close your eyes and dream

I'll give you back your key
But will you be happy?
Will you be happy?

Said we'll leave it alone
But I wont be here long
And when I'm gone
I guess then we'll know
