Short answer: no, Gemini aren't inherently two-faced; they're multifaceted. Ruled by Mercury, they switch lanes fast, which can look like inconsistency. If you've felt whiplash from a Gemini's changing opinions or social circles, you're not imagining it. Their dual nature is real, but it's about curiosity and adaptability, not betrayal. Think "both/and," not "either/or."
Context helps: Geminis mirror who they're with, sampling perspectives to learn. Ask what changed their mind, and request follow-through timelines to ground big talk. Keep texts concise, playful, and specific; they respond to novelty and clarity. If you're the Gemini, name your shifts out loud and keep receipts of commitments. Transparency turns "two-faced" into trusted flexibility.
