A Perfectly Good Heart

maybe i should've seen the signs, should've read the writing on the wall, and realized by the distance in your eyes that i would be the one to fall. no matter what you say, i still can't believe that you would walk away. it don'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?
