Since Cancer and Scorpio are both water signs, they also face many challenges despite having a strong and supportive relationship with each other. Possessiveness and jealousy are the very first disputes that they face because both signs can be possessive and jealous, which can lead to tension. Both the cosmic stars also possess intense emotions, which can sometimes cause conflicts if not managed well. Cancer & Scorpio, both signs, can be passive-aggressive instead of communicating openly and honestly. Scorpios can be prone to holding on to grudges without expressing why they are angry. Cancers can be more likely to take something personally and become hurt.
