Why??

He promised
He would love me forever
He promised
He would
But he didn’t.

He left me here
I don’t understand it
I never did anything
But love him.

And he left me
Standing beside the road
Waiting for him
He never came

He didn’t have to explain
The next day
When I saw him
With her.

What type of injustice is this?
What did I do
To deserve this?

He solemnly swore
To sacrifice everything for me
What ever happened
To make him change his mind?

What happened?
