At home in the Moon’s sign
Cancer is the sign linked to the Moon, so a Cancer Moon is very much at home, and your Sun’s there too, around the time of a new Moon. Everything goes through a feeling first. You’re happiest with familiar people in familiar places. You’ve got a great gift for caring for someone, as well as a shrewdness people often miss. Because you say so little, you might be excellent at a negotiation, and you may have an artistic side that needs a private place to work.
Since you’ve been hurt, or you’ve imagined being hurt in great detail, you may be wary of many people until they’ve proved themselves over time.
The tide goes out and comes back
You tend to brood, then overflow. Feelings build for days with no outward sign, and then something small, like a late reply, sets off all of it. A partner can be baffled, since they thought this was about the reply. Love is the main event for you. You nurture and protect, you need the same back, and you’re probably the one who remembers everyone’s birthday and how they like their tea.
The trap is that care can become a way of holding on. If you’re always the one looking after someone, they might find it hard to grow, or even to leave the house without a discussion.
Coming out of the shell
Say small hurts when they’re small, even if it feels silly. A partner can do something about a sentence. They can’t do much about a silence they don’t understand. Keep one area of your life just for you, like a class, a friend or a project, so that your whole mood doesn’t depend on one person’s tone of voice.
