Which is a common sign of an unhealthy relationship?

Excessive jealousy is often considered a common sign of an unhealthy relationship because it indicates a lack of trust between partners. In a healthy relationship, partners should feel secure and confident in each other's commitment and intentions. When jealousy manifests excessively, it can lead to controlling behaviors, emotional manipulation, and increased conflict, making it difficult for both individuals to maintain a sense of autonomy and mutual respect.

Healthy relationships, on the other hand, are characterized by open communication, mutual respect, and shared decision-making. These elements help foster trust and understanding, allowing individuals to express their feelings and needs without fear of backlash or resentment. In contrast, excessive jealousy undermines these foundational aspects, indicating deeper issues such as insecurity or possessiveness that can be detrimental to the relationship's overall health.
