Bc a relationship with a Capricorn is almost always followed by an immense amount of shadow work for both parties. People tend to forget that Capricorn is represented by The Devil in tarot

I hope this also convinces Capricorn’s that it’s not “karma” it’s just shadow work bc you awoke the demons

If you’re not doing the required shadow work within your relationship with a Capricorn, prepare to do it all afterwards, BOTH parties. That’s how it works

For clarification, this doesn’t mean Capricorn’s are “the devil” or incapable of maintaining a healthy relationship, it’s just pointing out the influence Capricorn has on relationships. The Devil in tarot represents the shadow self, attachment, self-imposed prisons, fear—
Capricorn brings all of these issues to light, and at times these issues are too big to tackle and the relationship fails, but sometimes growth happens and both parties mature and improve within the relationship and come out the other side the best versions of themselves.
This is why Capricorn is so concerned with the long-term, and so willing to plan for the future with you. Their goal is to improve and grow with you, come out better than before, but The Devil is a card of temptation, and its influence can be extremely difficult to overcome.
