Ah, Peaches, it's ok. You weren't being selfish, you were being a CLIENT. I'm guessing you don't usually invest this much in making your feelings known, so what you did was part of good therapy.

It's ok that you forgot about this -- you have to avoid being overly concerned with T's personal feelings, as a rule. But perhaps this can give you some potential insight as to why she might be replying in a very by-the-book way -- she might be overwhelmed. Her not replying may simply be because she'd rather talk about this all in person.

From where I sit, this new information makes me think your sharing an "I love you" with her, truly a special gift even if not fully acknowledge as such, comes at a very good time.
