No, I don't think it's taking anything from anyone else when you say 'i love you' to someone/anyone. Personally, I'd never say that to a t and I'd never expect a t to say it to me. I reserve love for those who share my life with me and I with them, and although my t knows more about me than anyone else, we really don't share a life and I know nothing about her except what she chooses to present as a t. I can't possibly love someone who I only know one part of...the professional therapist part. This is probably bc I became friends with my first t after I moved and was no longer seeing her, and I realized that all I had imagined about my t or how she was in her own life wasn't necessarily accurate. Guess it all depends too on how you define love. But if your comfortable with it and t is, then I don't see anything wrong with.
