Bella may find an unexpected ally in the vampire world. Maybe an old acquaintance of the Cullens who has a different view on the situation. This vampire could help her understand the unique aspects of her pregnancy, such as the twins' possible growth rate or any special needs they might have. This new friendship could also give her some protection from those in the vampire world who might oppose her having half - vampire twins.
Bella might rely on her human friends at first. She could turn to Angela or Jessica for emotional support. They would help her with day - to - day tasks like grocery shopping and going to doctor appointments. Also, Charlie, her father, could play a big role. He might be initially shocked but would come around to support his daughter.
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 might become more independent. She could start to rely on her human friends and family more, like Charlie. She would have to face the challenges of pregnancy without Edward's support, which could make her stronger in the long run.
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.
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.
Bella might cope with the pain by focusing on her love for the baby. She could keep repeating positive thoughts about the future with her child in her mind, which helps her to block out the physical pain to some extent.
One possible plot twist could be that the twins have some sort of special power. Maybe they can communicate telepathically from the womb, which causes Bella to have strange visions and Edward to sense something unusual even though he's left. Another could be that Bella discovers a hidden family secret about her own lineage that is related to the twins and their potential abilities. This could lead her on a journey of self - discovery while dealing with the pregnancy alone.
It often makes their relationship more intense. They become more united as they face the challenges together.
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.
Edward might be initially shocked and heartbroken. He has been in love with Bella for a long time, so her leaving for Jasper would be a huge blow. He could become withdrawn and moody, brooding over what went wrong.
He might try to find ways to distract himself. Maybe he throws himself into his studies or some other vampire - related activities. But deep down, he's still in pain. Every little thing around him would remind him of Bella. For example, if he sees a flower she liked, it would trigger a flood of memories and emotions.
