I don't think transference is a 'good' or a 'bad' thing, it's just something that happens sometimes (often!). I do think it can be useful to talk about, and it seems to me that discussing the connection you felt with him and exploring what it might have been about and what caused it to go away (or how and why you extinguished it) could lead to some valuable insight for you.

Also, you mention 'professional boundaries' and I just want to say that it is not your duty to uphold those - that responsibility falls on your T. It's okay to feel however you feel.
