How could you just leave?

How could you just smile and walk away?
How could you leave
but, tell me how you want to stay?
How could you purposely hurt me,
and say it's better this way?
What would you do if I just left you,
and never told you why I needed to?
What if I lied to you,
and hurt you.
Would you still want to be with me?
I just can't see how this could possibly be.
One second things were amazing,
but the next thing I know it's like it's all gone.
You were leaving me,
and for sure it was like a gun to the chest.
I was down and for the lost.
I was hurt and full of pain;
my life won't be the same.
Cause I'll have the scar
from where you hurt me.
A reminded,
of the shit you put me through.
