I think Bella and Edward are such a sweet couple!! Even though Edward is a vampire, bella still wants to be with him forever! They have such a strong love! It must be really really hard for Edward to keep control of himself all the time when he's with bella!!!
The thing i'm mad about is that edward left bella alone for i think over 4 months!! Edward left because he felt that he wasn't good for bella because of an incident that happened with Jasper. And so bella couldn't do anything to prevent him from leaving. That must've been so painful!!!!
