That's probably a good thing if you don't identify much with codependency. Hopefully that means that you have boundaries and a sense of self that are still intact.
Hope you find the other book useful. I thought it was one of those overall good reads- something you can apply to life in general, whether a close relationship, a work relationship, or any other. It a strange topic, one that's very common, and yet seems to fly under the radar much of the time.
