Would I say that I am his true self? Perhaps in a metaphorical sense.

I'm the part of him that you would consider "fucked up". You know all those strange thoughts and fantasies he has? It's me.
I am more than some Anima shrew that he needs to tame or some bullshit like that. No, I'm not controlling him, we'd probably feel better if I was.

Oh right, the whole self-hatred thing.
It feels like I'm the only part of his mind that's truly his, everything else is just what everyone wants him to think. In a way, we're both alone in his situation.
I tried to reach him through the mirror. Perhaps it was my absurdly voluptuous form, or maybe it was because he could see himself in me, but something made him want to run away, retreating to all the things he's heard a million times.

I think the worst part of all of this is the fact he's aware of it. He's aware that putting himself through this isn't doing any favours, but it keeps going...over and over.
