Uh, not a clue why you're asking.
So, no clue whether this answer will be anything near what you're looking for.

Attached ... as in romantically? I'm not. I'm a she & he's a he & we acknowledge that, but there's no sexual attraction. No, we've not discussed it--but he's been doing this 16+ yrs, I'm over 20yrs in therapy & it's not an issue in our work.

Attached ... as in absolutely resolved to continuing to work with him ... as in would be devastated were the relationship to end. I am.

What is it? It's commitment. It's knowing the relationship is a healthy one, based on mutual respect. I have placed before him goals for myself, and he has affirmed them as (1) goals he believes I am capable of achieving in the near future, and (2) goals he has the professional skills to teach me ways to obtain and incorporate into my life.
