Both these signs share a desire for escape. Sun in Pisces is focused on what lies beyond reality, and Moon in Sagittarius needs to have an adventure on the horizon. But Moon in Sag’s bluntness may clash with Pisces’ sensitivity, creating a spiral of misunderstandings and bruised sensibilities.
Sun in Pisces doesn’t always live in the real world. But his awareness of transcendent possibilities makes him a profoundly sensitive, creative and romantic partner. He’ll sweep in with the flowers his partner loves (and she didn’t even have to tell him what type of flower — he just intuited it). But if his lover makes things too uncomfortable or restrictive, Sun in Pisces is just as likely to sweep out. He may escape literally (by doing a fade-away) or (if he’s committed) he’ll be there in body, but check out mentally. His partner will have the odd experience of talking to someone who is not quite present.
Moon in Sagittarius needs a metaphorical open window in her domestic life. Her relaxed, playful expressions of love and nurturing can be uplifting for her partner, but she doesn’t enjoy domestic routines or traditions. Moon in Sagittarius functions best with a lover who doesn’t care when she leaves dirty dishes in the sink, or when she barrels over him with her needs. She’s doesn’t mean to be hurtful, but she’s not always sensitized to what others want. Her needs come first, because … well, she’s never considered why, they just do.
Sun in Pisces will be overwhelmed by Moon in Sag’s energy, but he’ll love her open acceptance of anything and everything. Finally, a partner who supports his crazy dreams! Moon in Sagittarius will feel enthused about Pisces’ creative visions, but in her eagerness to move forward, she’ll inadvertently trample his sensitivities. He’ll withdraw, and she’ll be confused (and eventually impatient). These two can bond over their shared love of freedom, but Sag will need to pay more attention to her partner’s vulnerabilities. Pisces will have to work on speaking up when she tramples over his boundaries, while realizing that the last thing she wants to do is hurt him.
