Like Mystic said Communications (verbal, non verbal and telepathic
) is > sex/intimacy > = finances.
If you cannot tell your partner anything in a declarative sentence, the sex/intimacy could be spetacular and he or she could be a multi-gajillionaire--lack of communication (verbal, nonverbal or otherwise) will instantly neutralize any form of relationship. Generally, it turns the relationship into a fling or a hustle/pimpin situation.
