An inability to find satisfaction without a certain person, someone must act a certain way and being a caregiver are some signs of codependent relationships. Another sign of codependent relationships is staying with a person in spite of behavior that is unhealthy, according to WebMD.
A codependent relationship is a relationship in which someone depends on another person's approval for self-worth and identity. People who were emotionally abused or neglected by their parents as teens are more likely to be in codependent relationships. To fix a codependent relationship, a person needs to set boundaries so that he can find happiness on his own.
