Aries often feels smothered by demands of family and even friends. Cancer, on the other hand, is very devoted to family needs and the inner, emotional needs of others. Aries may, without realizing it, selfishly accept Cancer's nurturing and giving, while contributing relatively little to the relationship on an emotional level. Aries' need for autonomy and independence often conflicts with Cancer needs for closeness, intimacy, and mutual dependency. Aries seems selfish, impersonal, and indifferent to Cancer at times, and Cancer may feel too needy and emotionally sensitive compared to Aries. Aries can learn compassion from Cancer and Cancer can learn to be more independent, but it's likely to be a rough road at times with much adjustment needed on both sides.
There is quite a bit of underlying tension between you at times, for your emotional needs, habits, and responses to life are very much at odds. Cancer has a strong need for security, closeness, and familiar comfort. Emotionally sensitive and sympathetic, Cancer needs to be needed, and is sometimes very anxious about Aries seeming independence. Aries is less bound to the past, to parents, or to family ties and traditions, whereas Cancer is a much more sentimental person to whom such things are very important.
Aries is often abrupt and impatient, and is not averse to fighting or being conforming. Cancer on the other hand, is very sensitive to disruption in the emotional atmosphere and to anything that is rarely the case! Cancer is not adept at picking up subtle clues and sensing or feeling the needs of others, but Aries is not! Cancer may secretly feel that Aries is selfish and uncaring. Aries may feel that Cancer is manipulative and overly dependent.
The flow of communication between you is often restricted, and very frustrating, especially for Cancer. Criticism and nitpicking can be a real problem for you. Aries wants Cancer to be very clear, very precise, and will constantly interrupt Cancer if there are inconsistencies in what Cancer is saying. Often you simply do not share the same interests or are just not on the same wavelength. Communication of practical, serious affairs is usually good, but any topic involving intuition or speculation is not likely to get very far. Because you communicate well only about certain topics, you both need other friends with whom you can share your other interests.
The two of you are fascinated by each other and strongly attracted to each other, but the distinct differences in your temperaments also inclines you to periods of personality clashes and misunderstandings. In particular Aries often feels that Cancer does not sympathize enough or try to really understand Aries' feelings. If you try to force each other to be more like yourself (or more like your image of the perfect mate), this relationship can be disastrous.
Cancer often checks or throws a damper on Aries' spontaneous impulses and self-expression, which is frustrating to Aries, and can be a source of resentment if it continues for too long. Cancer makes Aries question and doubt Aries actions, which can be a good thing in small doses, especially if Aries tends to be rash or foolhardy. However, Cancer must avoid becoming a "heavy" in Aries life, always the nay-sayer or disciplinarian.
The two of you are destined to have a rather unsettling affect upon one another. Your relationship may begin quite suddenly and unexpectedly, disrupting your normal routines and perhaps other relationships you are engaged in. There is an electric excitement between you which can be very thrilling, but also unnerving. Emotional impulsiveness and "acting crazy" together, doing things that are totally out of character or far more radical and daring that either of you would be inclined to do alone, are to be expected.
Sexually there will be many changes in your emotional relationship, so that at one moment the relationship is full of get up and go, and the next moment it is depleted or drained of energy. Aries may be turned off sexually at times with Cancer, due to the deep negative emotional state that Cancer gets into. Some problems may result from trouble with initiation at timing of lovemaking. Aries wants action, Cancer requires reassurance and patience. Expectation, usually leads to disappointment.
