I know exactly what you mean. I had a thought today: is codependency also a form of addiction? I have a lot of relatives on my mom's side (not my mom, but most of her family and my cousins), who have an addictive personality, and my father struggled with Alcohol, but he has been sober for a couple of years now. I've never been hardcore into substances, but I think I do have an "addictive personality" when it comes to certain things, so I just can't help but wonder.
