It was foolish, really.
Why did she think that anyone would love her when that obviously wasn't the case.
She fell and then they imprinted away from her; it was frustrating!
She had fallen for Sam, and he left her for her cousin who had been more like a sister and a best friend to her.
She fell for Jacob while he loved Bella then he had leaned on Leah for love when things seemed hopeless with Bella.
Then 'Nessie' came in to the picture, and he was all over her.
Jake loved the mutant.
What was the point in falling in love when no one could truly love her bitter self?
