"They never knew what they had until they lose it."

But what if I did?
What if I knew exactly what I had?

I tried so hard to hold onto it because I could never find something like that ever again.
I wanted it to last.
But I guess it was never up to me.

Isn't that worse?

Knowing what you had and it leaving anyways, despite your best efforts.
Knowing that you weren't enough to make it want to stay?

Isn't that what heartbreak is?
