Gemini With Cancer:

The homebody, introverted cancer may find club loving, outgoing Gemini way too hard to get for a good mate. While Gemini is constantly on the alert for changes and something new, Cancer is satisfied to become a truly domesticated mate, and ruts don't scare them. On the other hand, the cancerean moodiness may become too much for Gemini to cope with.
