Once a person is obsessed or addicted to a particular behavior, s/he won't make the decision to change unless they have suffered some losses. They need to realize that their behavior is causing serious problems for them.
Only then will they be willing to look inward.
Not trying to speak for Frank, but trying to understand what he's saying. I think he is showing what MWD is saying in her book, but thinks maybe some of us come on too strong. I'm guessing that is the misinformation he referred to, IDK.
To me, she is saying the same thing as we are....just using different words. We say boundary, she says ultimatum. We agree that if you set it.....you better be prepared to carry it out.
I do agree with the above statement from her book.
She saved that part near the end of her book, whereas some of use hit it up front with newcomers.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
