Audience is an important piece to this discussion.
If the assumption is that therapy is an option, then the audience for @ScoffingLizard's comment is very narrow - literate, health-conscious, a person of some means. It's good advice within that narrow audience.
For the rest of the world, though, it's abysmal advice. "Codependency" isn't really an accurate description of relationship dynamics in oppressive societies like Saudi Arabia or the harsh realities in the slums of Bangladesh.
