The hallmarks of a healthy relationship include open communication, trust between partners, teamwork, intimacy, and many others. Partners should talk freely about everything in their lives, including successes, failures, expectations, and everything in between.
Another sign of a healthy relationship is trust and integrity. Partners should enjoy solid trust with no secrets kept from each other. Healthy relationships should also have an interdependency aspect. Ideally, couples should rely on each other for mutual support while maintaining their identity as unique individuals.
Curiosity is another essential characteristic of long term love where partners show genuine interest in each other's thoughts, goals, and daily life. Other signs of a healthy relationship include playfulness or lightness, physical intimacy, teamwork, and excellent conflict resolution mechanism.
