Um, Eamon says something about how Cailan was a "good boy" had no chance after Anora "batted her eyes at him". Loghain remarks that Anora "led Cailan around like a puppy on a leash", and Wynne says, "Cailan loved Anora with every ounce of his heart. It was plain for all to see. The only thing that ever stood between them was you." (Although how Wynne would know is so far beyond me as to be totally baffling.)

I mean, it's possible that they're all wrong. Also possible that they were mistaking Cailan's affection for something else. *shrugs* I'll admit that I find Anora as a femme fatale almost laughable, don't think that Wynne is a great observer of the Anora-Cailan marriage, *and* think it's entirely possible that either Loghain wanted to believe they were happier than they were *or* was referring more to them playing a kids than any real affection. But...it is remarked on.
