How could you and what about you

How could you walk out of my life that fast?
How could you let me go?
Am I not special?
How could you not fight for me?
Do I matter to you?
How could you go far away and not keep in touch?
You left and you are never coming back?
How could you?
Do you ever wonder about what I am doing?
Do you ever wonder how I'm growing up to be?
What about me?
