This is true poetry.

This poem is a powerful piece, especially with the constant repetition of "we are not one" contrasted against "we are one". Not a word was wasted, and each was used thoughtfully to create such an evocative poem.
Your volta was like a tidal wave (goodness it was lovely), a strong emotional turn drawing the poem to a more personal end and the last line and "no one; not we, only I now, only me" were absolutely perfect touches.
Since you asked for feedback on your punctuation in one of your posts on the Feedback & Reviews forum, I took a closer look at it. It's great overall, though the lack of full stop on the last line sort of irked me. It's most likely a harmless mistake so you could just change that :)
Beautiful job and I'd love to see some more poetry from you! Keep going!
