Did you know?

Dependency on addictive substances has been known for centuries, but the concept of codependency got its name only as recently as 1979. For many of us, codependency isn't easy to understand; we may keep asking "Why doesn't she just leave him?" and find it hard to accept the answers we get. Codependents usually don't share their partners' addiction, but their lives tend to be taken over with the burden of caring for and protecting the spouse or partner. In recent years, people have started claiming that all kinds of conditions—anorexia, overeating, gambling, fear of intimacy, etc.—can result in codependency. Many experts think all of this has gone too far; still, almost everyone agrees that spouses of alcoholics and drug addicts face unique difficulties and should look for support and advice anywhere they can find it.
