I've told my T I love her, first in email and then later in person. She surprised me by signing an email "love T" once and I asked if that was a mistake! She said "no," and we talked about "therapy love ". She is a very kind and loving person; she probably loves most of her clients in that way. So it feels natural for me
to say and write "I love you" and to get emails signed "love, T." It's nice but doesn't seem so special anymore.
