Lots of movies, books and media *cough Twilight cough romance novels cough* hype romantic love up to be this grand thing which surpasses all other forms of experience. It's nice, but there's lots of other stuff which has to be in place, such as understanding, trustworthiness, stability, heart to heart and spirit to spirit communication.
Romantic love mostly comes from the gonads and tends to be strongest when there's a large element of uncertainty, tension and danger which shouldn't be present in a real relationship. Romance *by itself* is simply lust.
