The major reason my first relationship (at 28) failed was because of the love/approval addiction I had. At its core that was because of a set of dysfunctional beliefs I had about myself, and had little to do with introversion or extroversion. This is essentially why I'm suspicious of these labels because my experience of these traits time and again comes down to my beliefs, not some inborn characteristic I can't change. Thus the answer to your question becomes: Why would I want to go back to a set of dysfunctional beliefs about myself?
