I'm a Gemini with my moon in Pisces.
Apollo is an Aries.
Aries's independent, pioneering spirit is attractive to Gemini, who also values independence. If Gemini feels that Aries is being too controlling or if Aries takes Gemini's flirtatious nature too seriously, arguments may set the tone of the relationship. They create a good balance together: Aries wants to experience things and Gemini wants to discuss them. Together they can make all kinds of new discoveries that they might have missed alone. Both Aries and Gemini have tons of energy as well as common goals. Gemini is a thinker and a talker, prizes intellectual stimulation and freedom and loves to look at all sides of an argument. Aries loves to jump into new projects and get their hands dirty, and Gemini will definitely take the time to find out Aries's reasons for choosing the projects they support. While Gemini can be wishy-washy, Aries is straightforward and decisive; this is a great combination, but it is essential that Aries allows Gemini intellectual space. Aries is ruled by the Planet Mars and Gemini is ruled by the Planet Mercury. These Planets represent Passion and Communication, respectively. Because of their different approaches, Aries and Gemini work great in tandem -- they get their points across in different ways, but they definitely get those points across. Fevered debates will either spice up this union -- or ruin it.
Well they're certainly got his energetic playful nature down!
Athena is a Cancer.
Sensitive, emotional Cancer has trouble communicating clearly, but clear communication is what defines Gemini. Gemini's chivalrous nature and silver tongue may encourage the Crab to come out of its shell more quickly than usual; Cancer, in turn, can teach Gemini to slow down and appreciate the world, which the frenetic Twins hardly ever take time to do. If Gemini seems to ignore Cancer or doesn't provide them with as much reassurance and intimacy as Cancer needs, trouble may ensue. These two Signs approach the world in such different manners that they must be able to understand and accept one another's differences. Cancer is the Sign of home and hearth, while Gemini is the thinker. Gemini can easily slip into the role of Cancer's knight in shining armor; Cancer returns that favor with their characteristic urge to protect the ones they love. Quality of home life is important to Cancer, and Gemini will be spoiled by their Cancer lover's hearty home cooking, soft bed and other creature comforts. Cancer is strongly intuitive and maintains an almost psychic connection with their loved ones, but can tend toward possessiveness and idealization of their Gemini partner. If Gemini just reassures Cancer that they're loved and cherished, all will go smoothly.
Their signs seem to match each of them pretty well actually. Being represented by the God of War is a perfect fit for Apollo, considering his energy levels, constant desire to play and seek challenges, and our relationship being a give and take of challenge and compromise. Sometimes he's great fun, other times he's a little overbearing.
Athena is definitely very sensitive. Much quieter than Apollo and the "snuggler" of the two. I've always had to be sure to offer her extra love and reassurance because she seems to crave that on a regular basis. Sometimes she can be independent and playful, but she needs a reassuring pet or hug or scratch now and then to remind her she's in a loving, save environment.
