It can, depending on the type of therapy.

My T has an attachment-based approach. She acknowledges that there is some "re-parenting" type aspects to her approach (mainly taking advantage of transference and that type of thing), but she isn't my parent. Like Mouse said, it's more focused on having a better relationship than "re-parenting".

There's an added dynamic to our relationship that I am 22, and she has children that are my age. So there is probably a little bit more of a parent-child feel in our relationship than she might have with others. At 22 years old, there are things I still need presently from my parents at my currently stage of life that I am not getting. She does try to be there for me when those things come up. But she doesn't pretend like I am 6 or 8 and treat me how I should have been treated then.
