Welcome to the forum, salsa girl!
I have put two-and two together and realised that this is the practice that is known as 'marking'. It felt like everything about me was being watched.
They slipped up when they let you experience that before you committed. I heard my Ex talking about somebody at the hall being "marked", and saw how she suddenly refused to answer phone calls from another lady who just a few weeks before had been her best friend from the Kingdom Hall. Seeing this marking and shunning in action is one major reason why I wanted no part of the Watchtower organization. Another was when an elderly gentleman from the local congregation died from internal bleeding after surgery because he refused a transfusion.
So congratulations for getting out in time, before major damage could be done!
