I wish I knew a more definite answer, too, as I still am in struggle......yet I think as you heal, yes, the dependency/attachment feelings will evolve and heal and change too.
I know my attachment feelings have changed......especially since T took away hugs, I feel less strongly, intensely attached to her, yet I do still feel dependent on her, because I am not healed enough to not need her still. I have lots of healing left to do, and need the attachment and dependency and trust to do that healing......I think as healing progresses, I will feel differently, I will grow away from her (I hope, because if therapy ended next week I would be in a huge amount of pain from the severing of it, since I am yet very dependent.....)
It's a child grows into an adult and becomes more ready to leave home.....maybe I am still in the child phase of my therapy and not 'grown' enough, healed enough to leave......but the time will come, as my T says, when I will know, when I will not need her so much, and I will be able to see the end of therapy.....
