I am friends with all three of my FORMER therapists. Facebook wasn't a thing with the first two and barely a thing with the last. I doubt any of them would have sent me a friend request while I was still in therapy with them; they were all very professional.

However, hypothetically if they did, I probably would have accepted because boundaries were never really an issue. My guess is we would have simply liked each other's funny memes or liked great family pictures on each other's timelines and that would have been the extent of of it (that's really all it is in reality with them on facebook now).

I never had issues of jealousy about their families; I wasn't one to hunt for information about them or their families. They were very transparent about their spouses and kids, etc., so it isn't like anything particularly surprising would pop up. We're all pretty boring on Facebook actually. LOL!
