My old T, whom I only saw for about 4 sessions apparently looked up my husband on FB as I use a fake FB name. Obviously she knew his first name as my real surname and found him, it popped up on his screen as “Do you know xxxx xxxxxxx?” as a friend suggestion, 2 days after I terminated. We have no friends in common, this was when FB went through a stage of suggesting the names of any non friends who looked up your page.
