Heartbreak

Heartbreak is hard, and it's not fair,
We work so hard to gain their trust and then we get betrayed,
Its like Super-Man turning out to be the Joker,
after all those years of him saving every ones lives,
he finally takes some ones life,
He becomes evil,
and heartless,

He was my Super Man,
now he's my Joker,
my Grim reaper,
because he killed me inside,

What's he to you?
