Watery Cancer Moon is like the rain that falls from the sky. Fiery Sagittarius Moon is like a wildfire. Rain is a sure thing to put out a wildfire. These two just do not understand each other, and strangely enough, this is part of the allure. Sagittarius Moon needs freedom. It needs to be free to come and free to go. Cancer Moon needs to be protected and nurtured. Sagittarius Moon doesn't really nurture, not in any conventional way, and Cancer Moon doesn't let loved ones out of its sight.
If they get married, it's probably because Sagittarius Moon may have had no choice, and Cancer Moon isn't above making Sagittarius Moon dependent on it, at least financially. Sagittarius Moon will actually marry more than once in its life if it has to, but it will probably not be in love more than once. It is completely capable of marrying for something other than love. Cancer Moon is not.
The fighting usually starts before the wedding, but the wedding brings it out. Sagittarius Moon wants something exotic, perhaps an elopement. Cancer Moon throws a wet blanket on that. No way - getting married without family being present? An engagement ring that isn't a solitaire diamond? And what do you mean, you don't want to have children? Cancer Moon has a way of dealing with slippery Sagittarius Moon: it ignores what Sagittarius Moon says. Sagittarius Moon, in turn, just stops talking to Cancer Moon. Thus, they begin to drift apart.
Cancer Moon will certainly grow old, and Sagittarius Moon makes it old. Cancer Moon thinks it's Sagittarius Moon's parent, while Sagittarius Moon rebuffs any efforts to tame it. Cancer Moon wants Sagittarius Moon to grow up, be responsible, get a high-paying job, and eventually take care of Cancer Moon. Sagittarius Moon wants Cancer Moon to be happy for it when it changes its mind once again and wants to go live overseas or start a new career.
Sagittarius Moon often wonders why Cancer Moon is crying. Usually it is because Sagittarius Moon has said something callous and hurt Cancer Moon, who is far more sensitive and more sensitive to words. Cancer Moon lashes out, leaving Sagittarius Moon bewildered and wondering what they did wrong. By then, Cancer Moon is sitting in a corner, sulking. Sagittarius Moon can do nothing to fix the problem. Eventually, Sagittarius Moon stops caring about what it says and starts going out more, alone. It goes out for longer and longer periods, leaving Cancer Moon alone.
And one day, Sagittarius Moon announces that it is going to the store for some milk, and it never comes back. Cancer Moon thinks it was right all along, that Sagittarius Moon was no good, and it couldn't change it, no matter how hard Cancer Moon tried.
And that is the crux of the issue: Cancer Moon wants to save Sagittarius Moon from itself, even though Sagittarius Moon doesn't see a problem.
Cancer Moon likes sex to reinforce the intimate bond. Sagittarius likes to have sex because it is fun. Cancer Moon wants to set the mood. It turns down the lights, puts on soft music, gets naked, and lays seductively on the bed. Sagittarius Moon simply announces that it wants to have sex and just expects to get it on. It is the champion of the quickie, and it will do it anywhere: outside, inside, in other people's houses, in other people's beds, with other people in the room - when the moment is ripe, Sagittarius is ready to bite. Foreplay, cuddling, and pillow talk isn't really its thing. It would rather eat and go for a walk after sex than spoon and talk about the past, which is precisely what Cancer Moon wants to do.
Like everything else, this can end up with tears because Sagittarius Moon doesn't know why Cancer Moon is upset. If it didn't want to know what Sagittarius Moon was thinking during sex, it shouldn't have asked. How can the truth be the wrong answer, Sagittarius Moon wonders. How could Sagittarius Moon be so oblivious, Cancer Moon wonders.
The best way to make this work is to learn to cultivate a respect for each other's emotional needs but not really expect the other to fulfill them completely. Both partners should have lots of friends and family outside of the relationship to turn to when they need someone who understands them. It would be easier for both Cancer and Sagittarius Moon if they tried to focus on having fun together rather than having a life together.
This may also mean learning to do some things apart. Cancer Moon isn't so big on travel to exotic and dangerous lands, but Sagittarius Moon needs this. They shouldn't sulk or try to stop Sagittarius Moon from traveling. Likewise, Cancer Moon needs a nice home, and Sagittarius Moon should not thwart these efforts by making a mess of things or denigrating Cancer Moon's taste in décor or need to keep in close contact with family and friends. It may be best overall if they don't marry, since they are bound to drive each other insane, but they can learn a lot from each other if they learn to listen.
