pam's son is a college student and alcohol dependent. he still lives at home, and she often cleans up messes that occur when he is binge drinking. even though she wishes desperately he was not dependent on alcohol, she still feels like she somehow contributes to it. she tries to help him complete his assignments in school, even though they are really his responsibility, because she doesn't want to see him fail. what family factor discussed in your textbook is at work in this situation?
