Who is upset that the love between Bella and Jacob faded?

I feel like when I read Breaking Dawn, all the love that was worked up between Jacob and Bella just fell apart. I know he imprinted, and she is married but its like Bella just forgets how much she loved him and how much he loved her. Im upset it didn't end with Jacob imprints on Leah, him and Bella are best friends.. something like that but NOT the baby!!!!
