They...

The anger for a person is undescribable. They hurt you and your family. Then they leave without a trace.

The left because they couldn't pick up the mess they made.
They left to create a new life.
They left because you aren't good enough.

You are good enough they just need something better, not a broken family they left behind.

They wanted to see a family to fall apart.
They wanted to see their destruction of lives.
They wanted to see the pain of others.

You've been through the pain multiple times but you got used to it so now you are heartless because of them.

They broke you to pieces.
They broke the happy family you once had.
They broke your happiness.

Now you have to find a new shoulder to lean on, a rock, a person to count on, but for now be heartless so they can see what they created.

They created the monster.
They created the person that is going to create hell.
They created a person they will regret making into.

Now they will feel the pain they created to you.

They will see the person the person they made you into,
They will see the pain they created.
They will never see the happy you.
