I guess you have to read the book to understand that. the horcrux (the locket) was showing Ron his worst fears, which was hermione choosing Harry instead of him. In the book they have this great scene which they convientely left out of the movie, where Ron is upset about the locket where Harry tells Ron that he's never though of hermione in that way before and he sees her as a sister, he knows that Ron is in love with hermione and what not.
