Some of the things they did to each other were MEAN, and not funny joke pranks like it seemed it would be. Also, the entire book could have been avoided if they had just TALKED to each other about their feelings and why they were unhappy and hesitant to get married? Also, we didn't get a scene of them discussing how they would avoid going down the same path in the future. They just loved happily ever after, forgetting that they once were in love, hated each other and tried to get the other one to break up first, then back to love. Not exactly realistic. That pretty much sums it up.
