WHY IS IT THAT IF EDWARD HAS BEEN AROUND FOR SO LONG, HE DOESNT LIKE OLDER WOMEN?

It could be maybe cause Edward never had a first Любовь at all, he is totally new to that. Plus i think i remember Чтение something, that he might had been changed ages назад but that he still is like a teenager, somehow. So yeah thats just two theories, allthough i consider the first one more.

Because he likes girls near a school girls age.

because he looks so young and he would look stupid if he went out with say an 1000 год old woman wouldnt e an aslo bella is pretty !!

Because he has to wat for the "Right" girl. That is Bella and they will be soul mates forever.

Maybe because Ты know how he сказал(-а) he can read everyones minds except bellas...he probably fell in Любовь with her for that so thats probably why he didn't like some old lady:) Hope that helps

Although he's been living for over a century, he's still physically 17 years old. He is еще likely to be attracted to someone at around the same stage of maturity and development. The only beings who are as old as he is are fellow vampires, and most Вампиры would struggle to co-exist in a close relationship with a Cullen because of the human blood/animal blood issue. Also, the Cullens are trying to pretend to be human, and he knows that an apparent 17 год old dating a much older woman would attract attention to them.
