What was your parents' relationship like? Your placement in the family and relationship with your siblings growing up? How do you relate now with them and your parents? What was the source of the codependency you've already noted?
Also, when you say that the only person your H could depend on was you--didn't he have any friends? Did he already have a pattern of relationships which ended badly?
What changes would he need to make for you to take him back?
