Codependency is a compulsive behavior that happens in relationship where one person feels like they need to fix the other. This can happen among romantic relationships or within family members or friends. This commonly happens when the other person's life is consumed by alcoholism or depression, but it can happen in other situations as well. Codependency is a behavior that is subconscious and is not a diagnosable mental health condition.
