I’m sorry you are struggling with this, it sucks. My T’s wife has a very small bit that she does with his practice and I am afraid of the day I meet her. If you look at our interests and such you would think we would be instant friends if we were to meet in public. However, knowing more about her from google diving (T did not provide this info, nor does he know I have it) mt personality would likely set her off in a heartbeat. Sadly though right now this is all assumptions on my part and even if something were to happen it would be hers to figure out. I am not a threat to her or her relationship to her husband.
T’s web page has a blog that is done through a program that automatically give people the option to comment. No one ever has but I really wish there were opportunities for dialogue with others (clients or not as it is a public page) about some of the things on there. Personally I don’t care who knows I a working with my T as I believe everyone can use help at some point in their lives. Were my T to have a Facebook page like what I am imagining your T’s page to be I would feel disappointed that I was blocked. If T’s wife was office manager I can also totally see my T not knowing that/why I was blocked but I would ask about it.
I can also see where this is ethically “messy” with potential to be harmful. I have chosen to be in those “messy” places before and sometimes it works and sometimes it doesn’t. It is a risk we can only decide on for ourselves.
