Her.

She moves up to me from behind and wraps her familiar, comfortable arms around me.
"I am all you need, now and forever," she whispers softly in my ear. The warmth from her body shoots from my arms, up to my chest, and fills my head with painful memories. Her lips brush my neck and she caresses my skin up and down.
"I'm the only one who has ever cared about you, dear. How many times must we go through this? You'll always be mine." I shake my head in defiance and she quiets me.
"Why do you doubt me? I am your beginning and end, my love. Just accept it." Her breath is hot on my skin and sweat beads on my forehead. My heart pounds.
"Do you feel that blood pulsing in your veins? I am the reason you are alive. You are nothing without me. All you need is me. I love you, my baby. I love you and that is all that matters." I can feel her devilish smile as she rests her cheek on my shoulder.
We had reenacted this moment time and time again. This was not the first time she convinced me all I had was her, but it would be the last.

I lift my hands from my sides and remove her arms from my waist. I pull myself away from her and turn myself around to stare her in the face.
"I love you. I have loved you for so long. But I hate you and I hate what you have caused me to become." Her eyes grow wide and her jaw tenses. I can see her delicate hands ball into fists. "I no longer need you. I never needed you. But you held me so lovingly, you covered my scars and protected me from feeling. I don't want that anymore. I don't want you. What is life if you cannot share it with others? There are people who love me and deserve what I have to offer more than you."
I take her gentle face in my hands. I smile slightly and place my lips on her forehead. I kiss her face all over, her cheeks, her nose, her chin, and her lips.
"Goodbye, my sweet. I never have to be alone ever again."
