Good news! Glad he could come back with something that helped.
Maybe he thinks your regular T isn't serving you well? And hence was "surprised"? One thing that's really come across in this forum is how deep and strong the attachment is and how it might harm you, at this point, to give it up. Hence all the work you're doing outside of therapy, including the online T? Seems like he got that picture now, too?
Which is not to say that I don't think you could be OK if you did have to give the regular T up for some reason before the transference is resolved. Like he got sick or something. Just that I'm glad if this online T can help. Whatever it takes!
