I personally do not believe that therapy, in terms of the therapist-client relationship, can realistically model healthy attachment in everyday personal relationships. Let alone "fix" issues around it. It is far too limited for that, the entire structure and how it is done is way too unnatural. But this is just my opinion.

I was also intrigued by the comment that healthy people are not aware of their attachments, or I guess I do not understand it. People routinely miss others they like and are close to, go out of their way for loved ones and relationships in general. Maybe it's just not called "attachment" in everyday life, but things like love, friendship, companionship, etc. I would rather imagine that those that are unaware of these feelings and motives in themselves are either very young or... quite unhealthy emotionally?
