Jonathan, this is a sad little poem you've written, deserving of much more attention than it received. I enjoyed it very much. It certainly does have some quirky attributes, but that's okay. The italics threw me off a bit, especially where you split the word "s(weeps)", until I looked a little closer, that is. The straight type is the analogy of tearing construction paper and sweeping it away. The italics are the real message, about you or someone you loved tearing away from the other and ending your relationship, possibly in a less than honorable way. But even if it were honorable, it was still painful.
I think my favorite metaphor is the dotted outline of what might've been. That was choice, indeed.
It's so funy, because the poem was hard for me to get through because I'm a simpleton, but it made me cry at the end, ... "a dirtied, crumpled, cut-out [ -goodbye- ] s(weeps) across the sidewalk (because he couldn't.)" I guess it was those lines because it reminds me of something very bad that I've been doing, it makes me so sad, because well, he just can't, and I don't want things to turn out this way. Well, thanks for writing, hope to see more from you.
