Being dependent on another person can be unhealthy. Independence, taken to an extreme, can actually get in the way of us being able to connect emotionally with others in a meaningful way.
Interdependence suggests that partners recognize and value the importance of the emotional bond they share while maintaining a solid sense of self within the relationship dynamic.
A codependent person tends to rely heavily on others for their sense of self and well-being. There is an enmeshed sense of responsibility to another person to meet their needs and/or for their partner to meet all of their needs to feel okay about who they are.
When partners feel cherished and valued, the relationship becomes a safe haven and a place where the couple can be interdependent.
Allowing your partner room and opportunity to do these same things will be the key to establishing a healthy, interdependent relationship.
