Slightly frustrating book because it's almost impossible to tell who is talking. The dictionary form is used to show snippets of a relationship. It's sad, really, because it's a mess. At least one person cheated on the other. Anger, love, fear, acceptance. Will they make it? I don't know. Non-chronological as far as I could tell, though there are some parts that develop from one word to another further along. 
 I like the idea and found it entertaining. And I think I need to find a real dictionary for some of the words.
