I think my T created attachment at the beginning. I could call and email between sessions and he'd always respond in a short period of time. He was always very supportive, in and out of session. He wanted to create a safe place for me to open up. That gave me the positive experience I needed to open up to other people too. Later on in therapy he encouraged me to call or email him less and reach out more to my friends and family.

In short: he created attachment to make me independent. And that worked out really great.
