Both of you have strong, deep feelings and you bond very intensely. Consequently you become attached to each other and cling tightly to each other. However, your emotional natures are different in many ways too. Cancer often feels more compassion and sympathy for someone, while Scorpio may view Cancer's feelings as sentimentality. When wounded, Scorpio becomes resentful and vindictive. Cancer on the other hand, cries or sulks, and usually lets the other person know (verbally or nonverbally) about it. Scorpio, by contrast, hides it.
You may also have different attitudes towards sexuality versus love. For example, Cancer may feel that Scorpio is sometimes more driven by instinct and lust than by love, and this may become an issue in your relationship. Overall, though, the intense bonding and emotionality of your relationship fosters a deep, lasting attachment between you.
Both of you are very sensitive and intuitive about others' needs and feelings, and become deeply attached to people. The two of you can become very, very close, intensely bonded to one another, for you both need and seek a very complete emotional union with your partner. Cancer is very dependent on loved ones, and so is Scorpio, though Scorpio doesn't always show or admit it. When you want something or care about something or someone, both of you are very emotional and often lose all objectivity.
For the most part you are quite compatible, but there are some differences. Scorpio is more passionate, more emotionally driven, and has very strong loves, hates, and emotional reactions to people and situations (though these feelings may be hidden).
Scorpio's depths are revealed to very few, and it is difficult for Scorpio to be openly vulnerable and to relinquish control in a relationship. Scorpio can be very vindictive when hurt or angry. Cancer, on the other hand, is softer, more tender and gentle, and may be upset at times by Scorpio's vehemence. Cancer wants and needs a very sympathetic, nurturing, non-competitive and peaceful atmosphere.
The two of you have a very strong psychic or telepathic link, and there is a great deal of sensitivity, empathy, and understanding between you. Idealism and devotion are important elements in your relationship and both of you may gladly give or sacrifice much for one another. Cancer encourages Scorpio to be receptive and somewhat passive. Scorpio is easily swayed by Cancer's emotions and moods, and this may be confusing or overwhelming, especially if Scorpio doesn't have a solid sense of self. Cancer, on the other hand, idolises Scorpio, and may have a very inaccurate picture of Scorpio's true nature and needs. Also, both of you may be very indirect or subtle in your communications. Strive to be straightforward and clear with one another.
You enjoy dynamic physical activities together, and it is likely that you enjoy playing sports, competing against each other, and pursuing life together in a spirited, zealous manner. You are quite a "dynamic due" but you are also inclined to become angry with each other and feel initiated by each other. The dynamism and impatience that you arouse in each other can also lead to pushiness, power struggles, anger, and hostility. Sexual attraction is also very intense and builds up suddenly and unexpectedly.
Possessiveness, may be a problem in your relationship. Since your sexual desires come on fairly suddenly and strongly, you will find it hard to regulate them at times. Love and sex 'explode' in this relationship. You cannot get enough of each other. It can be an erotic combination.
You have a strong affinity with one another, an instinctive rapport that enables you to know one another very well, almost from the start. A basic compatibility exists which helps you to overcome the stressful or problematic facts of your relationship. You have a natural sense of belonging with one another.
Bursts of inspiration, creative imagination and insight, or strange psychic experiences makes your relationship lively and unusual. You may do some rather bizarre or unusual experimenting together. Avoidance of responsibility or reality can be a problem at times.
