Previously in time, codependent relationships were typically described as a relationship involving one person with a substance abuse problem with a sober (or generally non-addicted) partner. The idea of a codependent relationship regarding substance abuse is that the sober one continuously tries to help the person with the addiction. Seeing as how an addicted person struggles with their own issues and their focus is primarily on feeding the addiction, often all the work in the relationship to keep it functioning lands on the non-addicted partner. The substance abuse becomes the main focus of the relationship and the non-addicted person allows everything to revolve around their partner’s problem, often ignoring their own needs in the process.
