Co-Dependency:
Spouses depending on each other is not co-dependency. That would be interdependency, which should be a goal in your relationship. Co-Dependency is difficult for you to see when it’s affecting your relationship. Many people are in relationships that are chronically in turmoil which never seems to subside for very long, only to return to the same kinds of conflict.
Most couples come into my office complaining of communication problems, where each does not seem to understand the other. Discovering what Co-Dependency is and how it works is not difficult to understand, but does require counseling to work out.
