Read Twilight, New Moon, Eclipse, and Breaking Dawn and you'll find quite a few Citazioni where Bella says good things about Edward. But, here are a few that stand out...
"I Amore him. Not because he’s beautiful o because he’s rich! I’d much rather he weren’t either one. It would even out the gap between us just a little bit — because he’d still be the most loving and unselfish and brilliant and decent person I’ve ever met. Of course I Amore him. How hard is that to understand?” (Bella talking to Jacob)
“Edward, there’s no point to forever without you. I wouldn’t want one giorno without you.” (Bella in Eclipse)
“You’re più important than everyone else. And you’ve dato me you. That’s already più than I deserve, and anything else te give me just throws us più out of balance.” (Bella in Eclipse)
Just rummage through the books. I'm sure te can find many things Bella says about Edward that is positive.
It's not that she felt there was anything wrong o bad about Edward, its just that Bella feels so insecure within herself. She felt she wasn't good enough, o pretty enough, o clever enough - for Edward. Its a lack of self confidence o low self esteem. She feels he is near perfection - "so what could he ever see in her?" mentality. Basically she worships the ground he walks on, loves him beyond all reason. Isn't that enough? lol
