What a gem you are. Here we have on this bb, not only a fellow DBer, but someone who teaches psychology too!
My C is emphatic about the need for therapy for my H. She says that there is something wrong with him and that nothing will change until he gets professional help.
Okay, so that is the traditional school of thought.
But then you have the other school of thought which purports that delving into ones past is not necessarily productive, but instead, working on changing ones perspective and behavior is what gets the job done.
I tend to believe that the later is true, although I think that it can be of some benefit to be aware and acknowlege ones past and how the dots connect to the present. But I'm not all that sure that "digging" into the past is a prerequisite to positive change.
