Cancer and Sagittarius can be a challenging relationship to make work. The low scores represent the initial compatibility of this match. However, you are both strong willed enough to make this work, and if you succeed the scores would be much higher.
If you can both adapt to the others style this is a relationship which will improve steadily over time, and eventually rival any other match. The low scores represent a high initial challenge, and not a long term pessimistic view.
These scores show the averages for data collected from my clients over the past 20 years. It's important to note however that individual relationships vary enormously. This is a summarized picture, a real compatibility reading is needed to judge a real relationship. It's also worth noting that Soulmates can be found in any sun sign match, even those which are statistically likely to have low compatibility.
This article is in two halves, the first is written from the viewpoint of the Cancer man or Cancer woman, and the second is written from the viewpoint of the Sagittarius man or Sagittarius woman.
To understand your Sagittarius keep in mind that their role in life is 'to ask the hard questions'. Their mental and emotional toolset is designed to do just that - they're blunt, direct, reckless, carefree and easy going. Nothing holds back a Sagittarius for long, and no subject is off-limits.
Among that toolset is the ability to use analysis and humor to largely disregard emotions, whether their own, or other peoples. The centaur doesn't walk over others feelings, it runs! A very blunt speaker, Sagittarius isn't afraid to say what's on their mind at any given time. while sometimes this may make you laugh, at others it's almost guaranteed to offend you.
So, can you sit them down and explain the value of sensitivity and emotional connection? Not really, no. The challenge here is that they're like a child - far too innocent and well intentioned to really want to change them, while at times being fairly frustrating, no matter how much you love them.
It's likely that you'll be upset and offended more often by this partner than most others - either by personal criticism, lack of empathy, or just plain neglect while they go off on adventures. This is the original free spirit, spontaneous and reckless, always looking for something new or exciting, and usually in a totally care-free manner.
The root of the problems in this match then stem from the fact that you're emotional, while your partner just plain isn't. If you're feeling particularly perky and outgoing this is a wonderful partner to be around. Their outgoing confidence will always bring out your wild side, and you're guaranteed to have fun together.
When you want emotional support and understanding however, you'll find your Sagittarius just isn't very good at delivering consistently. Empathy just isn't their strong point.
Other areas of potential conflict include your desire for security, versus your partners need for freedom. Sagittarians place a high value on their independence, and you'll find you're probably ready to make a commitment long before your partner is. On the positive side of this, once a Sagittarius commits it usually means they've totally fallen in love - they don't do it on a whim like some folks might.
Physically, sex is likely to be fantastic in this match, and in the short term this works well. In the longer term however you'll notice there isn't always the deep emotional connection which you seek.
As in other areas of the relationship this may lead to you feeling dissatisfied and needy, quite possibly wondering if you have some kind of problem. Meanwhile your Sagittarius will be perfectly happy, and mystified as to why you don't feel the same way - again, unintentionally adding insult to injury.
While you're both passionate and romantic lovers, this fundamental difference in needs can make sex unsatisfying for both of you unless you take the time to understand your partner and respect their needs and viewpoints. Doing so will often expose you to new experiences you'll enjoy, so it's not nearly as self sacrificing as it might sound.
It's important to note however that we're looking only at sun signs here. There are many other planets which can have an equal or greater effect on someone's personality. Makes sense, as ultimately everyone is of course unique. Generalizing too far based just on sun signs can therefore be misleading.
To fully understand someone or how compatible you are with them we need to calculate those other planet placements from their date of birth, and compare them to your own, and then interpret the results.
This unlocks the real power of astrology, and gives much more useful and specific information: everything from how they view you, how to turn them on, how to avoid arguments with them etc. If you would like to explore this further please see the compatibility readings page.
A key thing to keep in mind in this relationship is that Cancer is a lot more sensitive than they first appear - they're a master at putting up a false front. If you're relative strangers, such as when first dating, this isn't a problem as they don't expect much else. However, as the relationship progresses they'll expect you, as a loving partner, to be able to see past that facade at all times.
Cancer is a sensitive and above all moody partner, who really does best with someone who intuitively understands them. To be blunt, this is unlikely to be you unless you focus on doing so. While you have a huge number of strengths admired by others, being overly emotional, empathetic or nurturing aren't high on your list.
In practical terms, Cancer is an unpredictable sign, while one day they may be fun loving and outgoing, the next they may be melancholy and down. While your partner is in a good mood, you'll get along perfectly - it can be a match made in heaven.
The problems arise however when your Cancer isn't in such a good mood, or feeling particularly sensitive - you just don't have the toolset to empathize very well - your first reaction will be to cheer them up via laughter and joking. There's a very high chance that anything you say or do in this direction is likely to make things worse.
Compounding this, Cancers tend to have phenomenal memories. If you say something considered offensive (and yes, you will) you can expect to have it quoted back to you during every argument for approximately the next ten years. Along these lines in most life areas you'll find Cancer is far more stubborn and inflexible than you are.
Other areas of challenge in this match include your other personality differences. For example, you're fun loving and reckless, while your Cancer is generally cautious and reserved. Risks keep life interesting for you, while most of the time your Cancer will run the opposite direction.
You like to socialize while your Cancer often prefers to spend most of their time at home or with family. You're honest and blunt, happy to discuss any subject openly, while your Cancer is far more reserved and private.
This is likely to be very good! Cancers are never dull - their varying moods ensure that you never quite know what to expect. This will certainly appeal to you, however keep in mind that however reckless your Cancer may be, they're here for true love - and expect the same. Cancers don't take love lightly, and ever implying that you do is likely to create a mountain of offense which you'll be hard pressed to climb out from.
So is this article conclusive? No! This article is based only on sun sign interaction. In order to provide a lot of people with information it's a convenient and fast way to generalize, but it's far from conclusive at this broad level. To get a complete picture we need to take all the other planets and their interactions into account for each of you, with a real astrology reading...
