No matter what you say, I still can't believe that you would walk away. 

It doesn't make sense to me, but:

 Why would you wanna break a perfectly good heart? 

Why would you wanna take our love and tear it all apart, now? 

Why would you wanna make the very first scar? 

Why would you wanna break a perfectly good heart?

 It's not unbroken anymore. How do I get it back the way it was before?
