Keep in mind that romanic love with one's girlfriend or boyfriend is only one of God's abundant blessings. If anyone worships it as God Himself, he or she will definately run into trouble sooner or later, even if they "successfully" exchange their wedding vows.
After all, we do not live in a fairy story where everyone lives happily with his/her beloved "happily ever after". In fact, even in a fairy story, they can live happily together ever only after the end of the story.
