Not A Nice Guy

I don't know what to say,
Or even where to start.
But I never would have guessed,
It would be you to break my heart.

Your attitude constantly changes,
With each passing day.
Do you even care?
What you do or say?

I really don't understand,
Why your acting like this.
I can't even remember,
When we had our last kiss.

Why do you say you love me?
When you treat me so bad.
All you end up doing,
Is making me so sad.

I really thought you were different,
I thought you were a good guy.
But I'm sick of always crying,
So it's time to say goodbye.
