Omg that was amazing!!! I loved it and am going to save it =)

I looooooved the line "I pulse in time with your veins".

The only thing that I'd change is I'd switch the last lines of the last two verses. In the second verse you mention you moving in time with his gestures, so I think it'd sound better for the last line to be him moving the pieces in your game. And in the last verse you mention things like his veins, his heartbeat, very deep physical parts of his being, so I think the last line should be him being the very letters in your name, or maybe it'd be better to make him a physical part of your body too. And I don't know about you being a book of empty pages, because if you had this wonderful person in your life who you are this close with, wouldn't your pages be full of memories of this person?

lol sorry to over-analyze it... but I only do that with poems that I really like!
Feel free to ignore everything I said
