Gemini's generally cheery disposition will lift Cancer's moodiness and Cancer's emotional lovemaking will fulfill Gemini's physical needs. Cancer is super sensitive even though Gemini thinks all will be smoothed over with superior communication, Gemini's flirtatious tendencies will hurt Cancer deeply. This is a short term relationship. Gemini hasn't the patience or the inclination to provide the security and home life that Cancer desires, and Cancer will not abide Gemini's tendency to explore all styles of relationships.
