So boring without you

I guess that means you're sorry
You're here, standing in front of my door
This means that you regret
All the things you said before
I really should not forgive you
But wtih you everything's so good
Promise you'll never go away
And you will stay here forever
I think we should stay together
You have the best piece of me
And frankly
My life would be so boring without you here
Something is not right
When you're out of sight
It's horrible to tell you goodbye
I really think I shouldn't care so
But you just let it go
Promise you'll never go away
And you will stay here forever
I think we should stay together
You have the best piece of me
And frankly
My life would be so boring without you
I should not have thought to let you go
'Cause here we go again
I shouldn't have heard you when you said goodbye
'Cause here we are together again

How could you go?
I should know...
You return
Promise you'll never go away
And you will stay her forever
I think we should stay together
You have the best piece of me
And frankly
My life would be so boring without you
