You mentioned that he left you before the Big Annual Gathering(BAG). Well that makes sense. You can expect him to call or text you after the Big Annual Gathering(BAG). You see the BAG is a large dating platform that single JW's attend to meet other JW singles. He is cutting ties with you to be free to date other female JW's. When he realizes that it didn't work out there, he'll be back.
But you better have some strong negotiation skills in place when he does. Start telling him, "You better put a ring on it".
