For clarification, the first part of the letter, which I had pieced together, sounded like it was going to be a love letter. He was talking about how love was a puzzle and usually the pieces fit together perfectly, but sometimes it takes a little bit of work and effort to put together. Then he started talking about our relationship and all the fun times we've had. Then came the last piece. He ended by saying that our puzzle was a waste of time and should have been left out on the table unfinished, where hopefully the pieces would get lost and the puzzle could be thrown away.
