So you got your heart broken again When you gonna learn they can't be trusted You've heard a thousand lies from a thousand men All these promises, they just got busted So you shut him down and you push him out And you're locking the door But they can't break your heart anymore Your guarded heart, your guarded heart So you're ready to live life on your own Go on and try it, it's now or never You can throw your weight by waking up alone I won't deny it, I can do better And now you're searching your soul It's a shame you don't know what you're looking for But they can't break your heart anymore Your guarded heart Your guarded heart You got a heart like a diamond It's harder than stone And it cuts right through me, right down to the bone Yeah, you're just like a diamond They can't let you go And they can't break your heart anymore Your guarded heart Your guarded heart Your guarded heart
