Bella may develop a stronger sense of self - preservation. Since she has a baby to think about, she'll be more careful about the risks she takes. She could also become more empathetic towards other single mothers in her community, as she now understands their struggles. Additionally, she might grow to resent Paul at first, but as she matures through the pregnancy, she could reach a point of forgiveness or at least acceptance.
Bella could become more independent. With Paul leaving, she has no choice but to rely on herself. She might become more assertive in making decisions for herself and her unborn child.
In this fanfiction, Bella's character could develop in many ways. At first, she might be in a state of shock and despair due to Paul's departure. But as the pregnancy progresses, she could find strength within herself. She may start to explore new interests or hobbies related to preparing for motherhood, like reading parenting books or taking prenatal classes. This could lead to her becoming more confident and self - assured. She might also have to deal with the judgment of others in the community, which could either break her or make her even more determined to prove herself as a capable mother - to - be.
Well, it could be that Bella decides to raise the baby on her own without Paul. She could focus on building a support network of friends and family. Another aspect could be that the werewolf or vampire community (depending on the context of the original story) has some sort of reaction to Bella's situation. For example, they might try to protect her from any threats that come her way because of the unborn child.
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 could also develop more compassion. Knowing she's bringing a new life into the world, she might start to see things from a different perspective, especially when it comes to the relationships within the Cullen family and their views on her pregnancy. This could lead to her trying to bridge gaps and bring the family closer together.
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.
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.
One possible reason could be that Paul represents a different kind of life for Bella. Maybe he is more down - to - earth compared to the often brooding Edward. Paul might offer a simpler and more straightforward relationship without all the supernatural drama that comes with Edward.
Bella might become more confident as she takes this step into a new life with Jacob. She could also become more assertive in dealing with the werewolf pack politics that come with being Jacob's wife.
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.
Edward might be initially shocked. He has always seen Bella as his own and this sudden change could be hard for him to accept. He could become withdrawn and moody, similar to how he was before Bella entered his life.
For Bella, show her growing strength as she faces single motherhood. Let her be determined yet vulnerable at times. For Edward, explore his reasons for leaving in depth, like maybe he was forced by some external threat. Show his inner turmoil.
