I don't necessarily mean "countertransference" in a negative way. Do you think that there are ways to tell if your T likes you on a more personal level (not necessarily romantic), or that they enjoy your company? Do they regularly extend the session beyond the 50 minutes you paid for? Do they allow outside contact? Disclose personal information with the aim of strengthening the rapport? Make daring (not inappropriate) jokes?

Sometimes my T does these things and it feels right in that I am able to open up a lot more when he doesn't keep strict boundaries. I also noticed that I tend to make more progress when he is more human. My need for him throughout the week lessens when he gives me "more" in sessions.
