Queen of Cups – Love and Relationship Outcome
The Queen of Cups in a Tarot reading is a fair and honest woman who will be friendly and of service to you, however, there are control issues and she is best heeded if not obeyed. She is intelligent and emotionally responsive with strong desires for the opposite sex making an excellent choice of partner for happiness and pleasure. She is very spiritual with the gift of vision and wisdom.
In the reversed position she cannot be trusted and can be a heart breaker and gold digger. There can be success but might be more trouble than its worth.

General Book of the Tarot
By A. E. Thierens, 
Queen of Cups
Fair woman, good honest and devoted; virtuous and one who will do service to the querent; another version says: “Loving intelligence, and hence the gift of vision; success, happiness, pleasure, also wisdom, virtue.” (Waite) Reversed: Vice, corruption, scandal, etc. A rich marriage.
The personification of the soul on the house of Capricorn, the Tenth, manifesting into the world that which it carries. As such this queen is to us the image of the married woman and the mother and of all that which woman can give to man and mankind, by her virtue both of soul and body. So the card must also mean the realisation of hopes and wishes, consequently success, etc. The ‘wisdom’ is here more of the practical blend, usefulness, knowing how to act with care and prudence. The card may represent a woman, or an impersonal power or authority, whom the querent has to obey, or to whom it will be to his advantage to submit. It expresses a tendency to go out into the world and make a name and position for oneself, and indicates the right moment to do so. It is fairly certain that it will ensure some publicity, renown, fame, or even glory or theatrical success, but of ‘scandal’ we see no indication whatever in the card itself, though of course ‘publicity’ connected with very evil influences might end in something like that. In such cases, however, we must not ascribe the effect to the card, which means publicity, but to that of the evil influences. It is a mistake, which we very often meet in the traditional interpretations, to ascribe effects, resulting from certain combinations of influences to one card which is only one of the composing causes.
The Oracle of the Tarot – Exoteric Tarot
By Paul Foster Case (1933)
Queen of Cups
The white rose in the vesica indicates the highest possible development of the character portrayed by this card, not by any means always met with.
From the beginning of the last decanate of Libra to the end of the second decanate of Scorpio, October 12th to November 11th, combining the rulerships of Mercury, Mars and Jupiter-Neptune.
She is mentally alert, yet somewhat superficial, probably has a touch of the poetic in her nature, and is kind-hearted, though not likely to go to much trouble for anyone. Has strong desires, and is emotionally responsive to the opposite sex. Very psychic, and if her higher nature is developed, is a very powerful spiritual force.
Gold-brown hair, blue eyes. Friendly to Querant if Well-dignified. If Ill-dignified, she is more subtle, decidedly coquettish, and may be even a deliberate heart-breaker.
