I agree. I see romantic love as an addiction to certain combinations of endorphins, adrenaline, etc. Chemical dependency, even though the chemicals are naturally produced by your body, directed by your brain.
Like a little wine or almost anything, really, it's okay in moderation, such that you remain in rational control of yourself. Once it drives you to self-destructive behavior, however, well, that ain't good.
You keep using that word. I do not think it means what you think it means. -- Inigo Montoya, 'The Princess Bride'
