Gemini (May 21 to June 20)
For a sign that shares everything -- often obsessively -- Gemini's living hell is being left in the dark. What is he really thinking? What did she mean by that? These are the kinds of questions that keep the Twins up at night. So, if you want to keep relations smooth, don't assume your Gemini knows what's up. They want to hear it from you, directly. Your consistent unwillingness to change or be flexible may also send this sign packing. And, being too possessive -- infringing on their freedom to come and go as they please -- can also be a deal-breaker
