Not everything is the fault of Aries and their occasionally insensitive nature, though. Sometimes, Cancer can be insecure beyond what is considered normal. It can often be tough for Aries to be constantly reassuring them of their love. All that happens is that Cancer becomes more insecure and Aries becomes more blunt and distant.
In terms of life attitudes, there is an immediate clash in values with this couple. Cancer is a homebody who loves small and intimate gatherings, curling up with a good book, and chilling out at home. Aries is adventurous, spontaneous, and often seeks out uncomfortable situations. Because of this, the pair can find it extremely difficult to identify activities that they can enjoy as a couple. Compromise is necessary here, but with such stark differences, it's not really worth the hassle.
