Attachment is part of any and every relationship, including every single therapeutic relationship no matter what type of therapy you're doing.

Attachment to a therapist comes with heavy transference, and typically amplifies the abandonment fears that stem from childhood/early life experience. Over time, the client and therapist work towards a secure attachment -- one where the client begins to realize that the therapist is still there and the relationship still in tact even if there is no contact.

But it does require a lot of time and a skilled therapist. Unfortunately, intense attachment and transference can certainly come up while working with a therapist who isn't equipped to handle it. When attachment and transference interfere in progress, it's time to work towards termination and referral to another therapist who is better equipped to handle things. This, too, can be done in a healthy way that, while it certainly amplifies feelings of abandonment, can ultimately lead to the best outcome as long as it is done at the right time and with appropriate care and communication.
