When a person becomes wrapped up in an addict's problems and makes excuses for them, this behavior is known as what?

The behavior described in the question refers to codependency. Codependency often involves a person becoming overly involved in another person's life, especially when that person has an addiction or other significant issues. This results in the codependent individual neglecting their own needs and well-being, as they focus on managing or supporting the addict's problems.

In this scenario, making excuses for the addict is a classic sign of codependency, where the individual may feel responsible for the addict's behavior or believe that they can "fix" them. This entanglement often perpetuates the cycle of addiction, as it can enable the addict to continue their harmful behaviors without facing the consequences of their actions. Therefore, the behavior described aligns well with what is commonly recognized as codependency in family life education.
