she was born in september so she either be a libra or a virgo. Not really boned up on the tarot and astrology connection, it never interest me on that aspect.
but..if anything has the "fire" in them..that would be me, i'm an aries.
Hmm... interesting
Well, if the card is significant of her, then it's probably outlining a fiery aspect of her natal chart.
Or as you say, perhaps it's symbolizing you yourself (as you're an Aries, the cardinal fire sign).
Now, I'm not sure about what kind of relationship the two of you had, however, on the aspect of getting back together, the Prince of Wands coming puts quite an interesting spin to it in the Outcome/Conclusion point (depending on the spread and the other cards ofcourse).
One way of looking at it is that there would be numerous struggles in the long run, but as time passes by, everything works out for the best. Another way of seeing it is that this is would be a passion filled affair, yet there would be a sense of intellectual stimulation as well (remember, this is "the air of fire"... the Vau of Yod).
Howeverwhich way you choose to look at it, one thing clear, is that both of you need to put aside issues involving your ego's (aries' whole alpha male thing going on... virgo/libra's whole perfectionistic everything should go this way thing). The main message of the card is learning how to compromise your selfish self-gratifying sides and learn to blossom in love. Be lavish with eachother in regards to affection, and learn to trust your intuition as well as trust her (and she trust you). When such trust is acheived, such can be a powerful bond that would keep the two of you together, side by side, ready and willing to take on every challenge and obstacle alongst your path.
Plus, on a sexual level, this is a card which in a way guarantees blissful experiences once willing to open yourself to eachother and explore every desire
Hope this helps.
