A theme of the book The Awakening is described as "the delusion of ecstatic love." Do you agree that "ecstatic," passionate love is a delusion?

You know those fluttery, swelling feelings you get for a special someone, when the love you feel for them is so powerful and overwhelming that it swallows you whole? Makes you understand all the passion in songs, movies, etc.? You know, those feelings that tend to fade over time.
Do you think those feelings are temporary because they’re artificial? Is that wild love really caused by the person, or by a general yearning? Is it all just a “delusion?”
