Relationships can be casual, platonic or romantic and involve trust, love, and mutual support. They can also be characterized by codependence and the ability to communicate effectively. In a relationship, partners work together to meet each other’s needs and help each other overcome difficulties. Relationships can be helpful in coping with stress, fostering good mental health, and adding years to life.

The most common type of relationship is a romantic one. In a healthy relationship, partners feel drawn to each other and can’t stop thinking about each other. Affection is what separates a romantic bond from a friendship, and it can include little things like holding hands or random kisses.

In an unhealthy relationship, one partner often puts their own needs and desires above those of the other. They may stay in the relationship even if they’re unhappy or if it doesn’t benefit them at all because they don’t want to be alone.

A family is another important type of relationship. Parents and children form a strong bond that nurtures each other. Siblings also share a unique connection that can’t be replaced. In general, relationships provide a sense of belonging and safety, and they can be a powerful force in helping people stay active and motivated to achieve their goals. In fact, research shows that having a supportive relationship is linked to physical and emotional well-being throughout the life course. For example, people in healthy relationships have lower rates of depression and anxiety and are more likely to be socially engaged.
