Short answer: sometimes. Capricorns aren't inherently passive-aggressive, but their stoic, goal-first style can look like it. When stressed, they may go quiet, default to curt replies, or "teach a lesson" by withdrawing effort instead of arguing. If you're getting mixed signals or slow replies from a Capricorn, you're not imagining it; this reserved earth sign often handles conflict indirectly to stay composed and in control.

The fix is clarity and timing. Capricorns open up when conversations feel purposeful, private, and calm. Name the behavior without blame, ask for specifics, and offer structure: "What deadline works?" or "How would you prefer feedback?" Set your own limits kindly and keep commitments; reliability builds trust. If you're the Capricorn, trade silence for one clear sentence about your need, then make a small, visible follow-through.
