What you waiting for lyrics - Lily Allen song

Since we separated
I've been suffocated, ah yeah
All the empty space in my head
First I felt liberated by it
But solitude is overrated
The other day I swear someone said
Someone else is sharing your bed
Maybe you picked up where I left
Now my heart is sinking
I don't know what I've been thinking

I turned a strong man weak
I threw him down, brought him to his knees
I'm hoping somehow he'll forgive me
I think to myself, what you waiting for?
You'll never be sure
Swinging back and forth
Just leave him alone-o-one
What you waiting for?
You'll never be sure
Swinging back and forth
I just don't know, know, know

Now the dust has settled
I should probably level with you
Meant it when I said, "I do"
Don't know why I was untrue
With everything I put you through
How'd it make you feel if I said I still love you
If I could go back, select all, press undo
Never thought we'd be this couple
I ran at the first sign of trouble

I turned a strong man weak
I threw him down, brought him to his knees
I'm hoping somehow he'll forgive me
I think to myself, what you waiting for?
You'll never be sure
Swinging back and forth
Just leave him alone-o-one
What you waiting for?
You'll never be sure
Swinging back and forth
I just don't know, know, know

Since we separated
I've been suffocated, ah yeah
All the empty space in my head
First I felt liberated by it
But solitude is overrated
The other day I swear someone said
Someone else is sharing your bed
Maybe you picked up where I left
Now my heart is sinking
I don't know what I've been thinking

I turned a strong man weak
I threw him down, brought him to his knees
I'm hoping somehow he'll forgive me
I think to myself, what you waiting for?
You'll never be sure
Swinging back and forth
Just leave him alone-o-one
What you waiting for?
You'll never be sure
Swinging back and forth
I just don't know, know, know
