Revealing mistake: In the swimming pool scene between Annette and Sebastian, a positioning mark can be seen quite clearly on the floor. [The swimming pool used was freezing cold, about 40 degrees, so Ryan Phillippe and Reese Witherspoon were freezing (look close and you can see Ryan shivering), and so were the camera crew, that they didn't repeat the shot, so the positioning mark was left in.] (00:28:05)

Cruel Intentions (1999)
Plot summary
Directed by: Roger Kumble
Starring: Reese Witherspoon, Ryan Phillippe, Tara Reid, Sarah Michelle Gellar, Selma Blair, Joshua Jackson, Christine Baranski, Louise Fletcher, Swoosie Kurtz, Sean Patrick Thomas
A tale of betrayal centering on two wealthy, manipulative teenage stepsiblings from Manhattan's uppercrust. It's summer break, and Kathryn has been dumped by her beau, Court Reynolds, for the innocent Cecile. Desperate to get even, Kathryn challenges Sebastian to ruin Cecile by deflowering her--thus humiliating Court by delivering Cecile to him as damaged goods. Sebastian has pretty much 'had' all of the girls in New York City up to this point, and he's gotten a bit bored of it all. Though this is too easy a conquest for him, he obliges. He sets his sights on a higher challenge--the headmaster's daughter, Annette, who recently wrote an article in 'Seventeen' Magazine about how she intends to stay pure until she marries her boyfriend. Sebastian bets Kathryn that he can seduce the chaste and pristine Annette. Kathryn believes it impossible, and agrees to the wager--and if Sebastian succeeds, Kathryn must give him a night of unbridled pleasure, something he's wanted since their parents got married.
Kathryn: So I assume you've come here to make arrangements, but unfortunately, I don't fuck losers.
Trivia: This movie is a retelling of the story of "Dangerous Liaisons."





Answer: A bit of both. I believe that Ronald did love Cecile. But I also believe that Kathryn manipulated him in such a way and so much that he eventually gave in to his masculine tendencies. He's only human, after all. He wasn't anticipating Kathryn telling anyone, let alone Sebastian finding them in the act.
