Short answer: usually no. Wondering, 'Are Sagittarius cold?' They're not naturally icy; they're independent, blunt, and busy chasing experiences, which can read as detached. If a Sagittarius left you on read or keeps plans loose, you're not imagining it - that's their freedom-first wiring. When they care, they're generous, enthusiastic, and upfront, often warming fast once there's shared adventure or honest conversation.

Context helps: fire signs express warmth through motion, not constant check-ins. Timing and the rest of their chart (Moon, Venus, rising) shape how cozy they feel. Want more warmth? Offer low-pressure plans, share your curiosity, and say plainly what connection looks like for you. Avoid guilt-tripping or ultimatums; they shut down. Set your rhythm, too - if you need steadier contact, ask clearly and notice how they respond.
