@ds, i agree.
there are three motive of study in psychology; cognition (thought), behavior, and affect (outward portrayal of emotion), and couldn’t you say that some aspect of love fits into all three of these categories?
you can love some one without meaning too, which is more of an emotional (or cognitive) quality, or you can choose to acknowledge that you some some one, also sort of cognitive, but being able to act (behavior) as if you love some one, and show (affect) the person real emotions in a way that is consistent with what you’re feeling (cognition), that, I would say, is more of an ability.
An ability that comes easy to some, and with a great amount of pain and labor to others.
summary: love can be an emotion when it is purely cognitive, and an ability when it becomes a behavior.
