SummerTime, It sounds to me like your T was being very authentic and honest. Especially because he concluded his statements by saying that "that door could never be opened" and "we will have a healthy relationship".

Now, having said that...I do think my little hairs would start to go up if he begins to go down this line of discussion more frequently. I wouldn't want to hear him carry on about how much he wishes the two of you could be pals outside of therapy. He has made his feelings known very clearly (and seemingly appropriately) in a context that hopefully normalized your own feelings...but now he needs to focus solely on you from this point forward...and leave his own stuff out of it from here on.
