That was interesting to read your observations as an outsider. It reminded me a lot of my first meeting on a Sunday. I was in college at the time. I had been given the watchtower ahead of the meeting and read it before I came.
I could not believe either that they actually read the paragraphs aloud. Then they recited most answers out of the magazine. I found it mind numbing. After the first meeting, I made sure I had to be at work early and only attended the public talks. They were a little more interesting because I had not already read them.
Be careful, though, because the love bombing is much more effective than you realize. They may be sincerely friendly, but it is always with the objective to make you another drone like them.
The public talks are issued straight from the society and are recycled, as you say. Sometimes you want to just scream when you hear the same talk for the tenth time and could easily get up and recite it for yourself.
Good luck with your girlfriend.
