I also wonder why I am so much more attached to my T than I was to my mother. My Mom died many years ago. I was attached to her, but did not feel close to her. Does that make sense? She was overprotective, and I had difficulty separating from her, yet I did not share with her any of the problems I shared with my T.
Miss C., I think it is logical that the closer we are to our T, the more we wish we could have that same relationship with our mothers. Just my opinion, of course.
