Once the big reveal happened that Amy was framing her husband, the book became really predictable.  I thought the initial idea of the Amy diary was clever and how she framed him, but it left everything else lackluster and dragging on.  I never found myself rooting for any of the characters.  I felt the ending was flat and without any impact.  I would have ended it with someone dying or something.  Them continuing a fake relationship was not satisfying to me.  Overall it could have been good but instead just became annoyingly predictable. 

Question: How is the plot?
