We are all so different. It would be much easier for me to say I am in love than to dismiss my relationship by saying "it's transference." Also, your T may offer you her interpretation of what she thinks it means when you say "I miss you", but it isn't necessarily correct. Only you know. It is the responsibility of the client to tell the therapist if his/her interpretations are correct. You may truly be missing her, and it's OK to feel that way and it is OK to tell your T that her interpretation is not correct! You are the expert on your feelings and thoughts.

I feel an absence, like there is a piece missing from my life. A bit of an ache. Sometimes I don't realize how much I really missed him until I am back in his office, sitting down on his couch, and there he is before me. And I suddenly feel it most strongly then, like by contrast do I know it. I feel both him and "us" again. Sometimes at those moments he will say, "it's been a long time." I always like that, because it means he is feeling something too. I have got to the point where I can smile and say, "I missed you." (Rainbow, if at that moment, my T said "well, you really didn't miss me, you just missed the good feelings that come from being in therapy with me, plus part of it is transference," I think I would deck him one. That would be highly insensitive of him and deserving of a swift kick in the kazoo--as my mom liked to say.)
