Gwen Stacy: She's Eddie's girl, sort of, but she has a major crush on Spider-Man. Inadvertently, Gwen fuels Eddie's hatred and hurts Peter's relationship with M.J., but when she see's Peter's darker side, she wisely chooses to walk away.
Spider-Man 3
Things are just beginning to go well for Peter Parker. He has found the balance between being Spider-Man and having a life of his own, and he has won the girl of his dreams. Good times never last long for Peter, though, and even with three new powerful villains - Sandman, Venom, and the New Goblin (Peter's friend Harry, who turns on him after finding out that he is Spider-Man.) - his greatest battle is within himself.
