The Twilight book series has been thought of as promoting abstinence, so I've followed it somewhat because of my work. I found it interesting to read this post, which goes through the checklist from the National Domestic Violence hotline for Bella and Edward's relationship, and finds 15 signs that their relationship is abusive. Fifteen! I have only read articles about the books and movies, not read the books or seen the movies myself, so I am frankly surprised to hear that Edward throws Bella through a glass table. But even the other signs, like repeated statements of jealousy, abandoning her in a dangerous place, threatening suicide. . . This is supposed to be romantic? Religious groups can't possibly approve of these books, abstinence message or no.
