Actually, I'm 27, and more than aware of the kind of relationships people have at 16. What I meant by that statement was that emotion "love" is a threshold like pain, and without having dated much to get perspective on that threshold, things can seem more intense than they might really be. If you've only ever felt romantic feelings for one person, then you don't know the difference between that kind of love, puppy love, and real honest love. You should have several kinds of relationships, both good and bad, give and take, and the break-ups and pain to go with those experiences before you really learn to appreciate what's "real."
My insinuation, if there was one, was that at 16, it's doubtful either have dated enough to be able to sort out that kind of complex relationship from the usual rush of hormones.
