How Is It?

How is it that I can hate someone who I love, with the same ferocity?
How is it that I continue to breathe after my heart has been pulled from my chest?
How is it that the one I sought to hold me & dry my tears has become the source of those tears?
How is it that the world doesn't stop to notice that I'm on my knees, begging for just one moment of solace?
How is it that the one who asked me to take down my walls & trust him, is the same one who has reminded me why I had them up in the first place?
How is it that I'm expected to believe that my heart continue to beat, without the only one who has ever been by side?
How is it that one day, this will be nothing more than a painful memory?
