Bella's character development in this fanfiction is quite a journey. After Edward leaves, she is likely in a state of emotional turmoil. When she becomes a vampire, it's like a rebirth. She has to adapt to her new senses, which can be overwhelming. This forces her to become more in - tune with herself. She may start to question her past decisions regarding Edward. Her new vampire life also gives her a chance to redefine her purpose. Maybe she becomes more involved in vampire politics or uses her new abilities to protect others, which shows a more selfless side of her that was perhaps overshadowed by her relationship with Edward before.
Bella's character might become more confident. Without Edward, she has to rely on herself, which forces her to grow. As a vampire, she'll be more physically capable, and this could translate into mental strength as well.
She develops in multiple ways. At first, she may be angry and hurt by Edward's leaving. But as she becomes a vampire, she starts to see things differently. Her new vampire instincts might make her more assertive. She also has to learn to control her powers, which teaches her discipline. Her relationships with other characters, like the Cullens who may or may not be involved still, will also shape her development.
In such a fanfiction, Bella might experience a whole new life. She could gain new powers and abilities as a vampire. For example, she may have enhanced strength and speed.

Often, it develops as they face external threats. Enemies from other vampire covens may target Bella because of her connection to Edward. As they fight off these threats side by side, their love and trust for each other grow. In many fanfictions, there are also emotional challenges.
