Answer:
"Bella actually falls in love with Jacob in New Moon. It's understandable why this fact didn't occur to her: Bella had fallen in love only one other time, and it was a very sudden, dramatic, sweep-you-off-your-feet, change-your-world, magical, passionate, all-consuming thing. She didn't recognize the much more subtle falling-in-love she experienced with Jacob. She was only aware that she preferred being with him over everyone else, that he was constantly on her mind, and that his happiness was essential to her own. She also enjoyed being physically close to him in a way that she didn't with her other friends. But it took her a while to add up all the pieces."
