Those are really good questions. In terms of what it would mean to me, I suppose it would confirm an acceptance of me, in spite of all I've told him, and also it would somehow acknowledge the way our relationship has evolved. When I met him I was highly guarded and saw him as a consultant T while I decided whether or not to return to T1. I was terrified of being hurt again and would not let him in any further than was absolutely necessary. Now I have told him some deep things, and he has never changed. That's a consistency and acceptance I've never felt before.
With regards to what I want from a hug, well, I'm not sure that I do want one. The thought is comforting, but it would feel weird I think in reality. I'm not sure. I guess I probably need to discuss it with him!
