I liked this well enough, but wanted more from it. The drawings of all the stuff Min was returning to Ed were a little distracting--if it was meant to be the actual stuff, I think photos would have worked better. And I'm disappointed in the ultimate reason Min and Ed break up. Min gives so many small-but-valid reasons all throughout, but (view spoiler)[it's not any of those, exactly, or even a combination of any of them, but rather a whole different thing. (hide spoiler)] 
 I do vaguely worry that it sets the stage for "he doesn't beat me/cheat on me/scream at me, so therefore there's no reason to break up" even when the relationship doesn't work for many other reasons. "He meets the basic requirement of human beings" isn't a compelling reason to date someone, and I worry that's the take-away message teen girls may get from this book. 
 (Blah blah works of fiction not morality tales blah blah fishcakes but it's hard to deny that teens DO take messages away from what they read) 
 **For a similar idea--a relationship and its demise told through STUFF--see Important Artifacts & Personal Property From the Collection of Lenore Doolan and Harold Morris, Including Books, Street Fashion, and Jewelry, by Leanne Shapton. Aimed at adults and experimental but a similar premise.
