People who share a long trek, three weeks across a mountain range, learn things about each other no cafe conversation would ever reveal: how the other bears hunger, how they decide when it rains and there is no shelter, what silence they hold during a hard climb. Your Descendant in Sagittarius recognizes the one who walks with you like that. Jupiter rules your relational face here, which means the other who stays in your life brings wide horizons, a hunger to know, a frankness that laughs out loud and does not take offense easily. The partner, the central alliance, the strong accomplice shows up as a travel companion in the literal sense and the philosophical one, someone you can grow the frame of reference with. You find magnetic the one with long projects, who reads, who travels, who asks the big questions. What snags you isn't relational restlessness. It is mistaking the shared horizon for an agreed escape, leaving together so you never have to stay in the near thing that was already asking for depth. The journey is also a place to stay. Look at whether your companionship also holds the slow conversations, not only the big maps. Plant something of your own inside it.
