"But that ultimately, they are not for each other."

And that is from your link.

I think there alrite 2gether but Ron + Hermione and Harry + Ginny shood b 2gether xx :)

"Rowling maintains that Harry's true soulmate is Ginny, and that even though Hermione and Ron have shared moments, they are ultimately destined for a close friendship."

I'm assuming they mean "Hermione and Harry" have shared moments, because Ron and Hermione get married, so obviously they are more than just friends.

Couldn't have said it better myself, elstef.

Thank you Poseidon3.
