How is it this way?

I don't know why
Your memory still haunts me.
I don't like you anymore,
So why does this bother me?

I feel nothing towards you.
You are now a ghost to me.
You had your chance,
And you blew it, you see.

I found someone else,
Someone who is better.
I would have told you sooner,
But you're not worth the letter.

It's strange though,
And I don't want to face it...
When I thought I might see you again,
I got nervous and had a fit.

I really don't like you,
So why is it this way?!
I feel nothing for you,
How many other ways are there to say?!
