An interesting write. I love Twilight myself, so I love to see poems about the series :)
Not exactly a standard poem, but the way you have interlaced the quotes with a running theme makes it interesting and adds a hidden spark to the piece.
I love the 'unheard heartbeat' part, so true yet the 'I know.' holds so mcuh emotion!
One small problem - at the start (and in the title) 'You' should be 'You'll' Apart from that, it's fine!
