Family is central to both Edward and Bella's lives. While Bella has grown up close to her mother, she has an understandably awkward relationship with her father Charlie. Though Charlie gives Bella plenty of space, he does watch over her like a protective dad. The Cullen clan has a more complex family dynamic. The Cullens are bound together by their "diet" – none of them prey on humans – and the fact that Carlisle adopted each family member. Though none of them are blood-related, the Cullens understand each other like no humans can, and have genuine affection for each other. Interestingly, the human family (Bella's family) that we see has divorced parents, whereas the vampire family includes several committed, happy marriages.
