Peace and harmony in life is a top priority for both Cancer and Libra. However Libra is a lot more open minded and rational than private and emotional Cancer. Libra's strive to meet new people and see new places might not be appreciated so much by jealous Crab. Cancer usually wants to be pampered or to pamper his partner, and for Libra this is alien as Librans believe in equality and that everything should be balanced. Overall not the best match, but can still work out if the two can sort out their differences and change themselves to some extent.
