The question is - do you have problems with attaching to people? Are you able to do this? Because if the answer is "yes, I have a problem with this", I would say that when you finally are able to attach to your therapist it means that therapy works and you're both doing a good job in creating a safe relationship. And then you will be able to attach also to other people in your life (when you understand why it was hard to trust people or this kind of stuff).
(as I understood good attachment is important thing in life)
And if you do everything to not to be attached to T you just won't fix this problem.

But maybe it's not a problem for you and you work on completly different stuff and it doesn't matter at all in your case?

For example, for me, it's difficult to attach to people and I want to finally be attached to my T. Because I know that it will be a huge step for me.
