I don't think you sound too attached at all or that your therapist is doing anything inappropriate. Remember, attachment is critical in many types of successful therapy. The standard I go by is if I am making progress, the therapy isn't broken, so why fix it?

Everything you wrote sounds fairly typical to me. Certainly there is a range of therapeutic styles, and some will be stricter and more of a blank slate than others, but that's not a gold standard, just another approach.
