As two cardinal signs, Cancer and Libra go after what they want in very different ways. Cancer feels out new people emotionally, and may not sense a safe harbor with airy Libra. Libra's initial modus operandi is to be aloof and observing, and Cancer may find this too risky. Libra finds Cancer a muddled thinker, too tossed about by their emotions. But both sense someone substantial, and perhaps the real thing. Libra seeks partnership, and Cancer aims to create a secure home -- if there's timing, a commitment between them ensues.
What bonds them is a shared desire for a harmonious home life. Libra's fixation on the relationship eases the insecurites of the Crab. This is an affectionate pair, focused on fulfilling the needs of the other. They both shy away from conflict, and this could lead to repressed anger with the potential to be destructive. It's key here to trust each other enough to be truthful, even if it temporarily upturns the apple cart. The other issue is socializing -- Libra may want to hit the town, while Cancer is happiest at home or with a few close friends. But Cancer and Libra don't mind making compromises that enhance the relationship, and this ups the chances for an enduring life together.
