How can a writer develop the characters in an 'Edward leaves Bella pregnant' fanfic?

She might first be in shock. Then, she could turn to her friends like Jacob for support. Jacob, being protective, would likely try to help her in any way he can, whether it's providing for her basic needs or just being there to listen to her fears and concerns.

She could be heartbroken. After all, she's pregnant and the person she loves has left her. She might feel abandoned and alone, crying a lot and wondering why Edward would do such a thing.

Bella may become a more adventurous character. Maybe she decides to try new things that she was always too afraid to do before because Edward was so overprotective. She could start going to parties, trying extreme sports, or exploring new hobbies. This new adventurous side of her would make her a more well - rounded character, and when Edward returns, he would see a completely different Bella.

Bella might develop into a more confident and motherly figure. Since she's been through pregnancy before, she would be more prepared this time, but still face new challenges. Edward, on the other hand, could become more conflicted. He loves Bella and their unborn child, but is constantly worried about the dangers that lurk. Jacob, if he's still in the picture, might be a bit jealous at first but then come around to support them. He could also be a protector of the family in his own way.

Bella often becomes a stronger character. She might start to focus more on herself and her own growth. For example, she could learn self - defense or focus more on her studies. As for Edward, he usually realizes his mistake in leaving Bella. He may go through a period of self - loathing and then try to find a way to come back to her. In some fanfictions, other characters like Jacob become more important in Bella's life during Edward's absence, and this changes the dynamics between all of them.

It could be that there are external forces at play. Maybe there are other characters or some kind of dark secret in the fanfiction lore that forces Edward to leave Bella while she's pregnant. For example, there could be a threat from a rival group that says they'll harm Bella and the baby if Edward stays, and he thinks leaving will draw the danger away from them.

The baby could also be a tool for character development. As Bella and Edward (if he comes back) interact with the unborn child, they might discover new aspects of their personalities. For example, Bella could become more nurturing than she was before, and Edward could become more accepting of the idea of a family, which was something he was hesitant about before.

One idea could be that Bella has to raise the baby alone at first, but then she discovers some hidden powers within herself because of the pregnancy. Another could be that the Cullen family, despite Edward leaving, secretly keeps an eye on Bella and the baby, leading to some tense and emotional encounters.

Bella often becomes more confident in her relationship with Edward as his wife. She may be more assertive in making decisions for their future together.

For Edward, he'd be a lot more serious. He has to think about providing for Bella and the baby. His carefree vampire side might take a backseat. Bella would change in that she'd be more in tune with her maternal instincts. She'd be more cautious and perhaps a bit more secretive about her pregnancy in the beginning to avoid unwanted attention. And as the pregnancy progresses, she'd become more dependent on Edward for physical and emotional support.
