Here we go again

It's not mine, but SO TRUE!

I throw all of your stuff away 
Then I clear you out of my head 
I tear you out of my heart 
And ignore all your messages 
I tell everyone we are through 
Cause I'm so much better without you 
But it's just another pretty lie 
Cause I break down 
Everytime you come around 
O Oh O Oh 

So how did you get here 
Under my skin? 
I swore that I'd never let you back in 
Should have known better 
Than trying to let you go 
Cause here we go go go again 
Hard as I try I know I can't quit 
Something about you 
Is so addictive 
We're falling together 
You'd think that by now I'd know 
Cause here we go go go again
