Answer me Why

Can anyone answer me why it hurts
To fall so hard on all his words
To fall for all his little smirks
And to love all his little quirks?
Someone try to answer me this
Why can't he see that something's amiss?
Can't he see the pain in my eyes
The pain I don't realize
I've let shine straight through
And made myself feel blue?
Maybe I've answered my first on my own:
He never realized the emotions I've shown
And even though I knew his kind
I let him get inside my mind
Why can't he just open up and see
That all he does is killing me?
So, can anyone anser me why it hurts
To hear him say those farewell words?
