how to get a cancer you hurt back?

How long ago was this?

He won't believe it until he sees it unfortunately.

Cancer sun, gem moon, Libra rising here. If he has a magnetic attraction to Aries and Libra women like I do, you won't be rid of him so easily. Cancer males invest a lot, and I do mean A LOT of emotion into those they love and will see their investment through to the very end. They are gamblers with their emotions, risking everything for the best reward. This doesn't mean to be passive, or to take it for granted. Do this, and he will immediately be done with you.

If he has retreated, he still won't go back to his loving self until you show him you want it. He needs to know you miss him as much as he misses you. If you do try and express these things and he is unresponsive, he might need more time to cool down. However, there is line that is crossed when being hurt and cooling down, turns into being a selfish, woe-is-me brat.

Actions mean much more than words, and if you show that you love and care for him, this should be all that is needed to get communication flowing again. Keep that in mind if it doesn't.
