Bright, I'm not surprised that he's on FB. It's another part of experiencing something different and wanting to stay in touch w/others and yes, meet new people as well from all over the world. Whatever the reason, he's changed his mind about FB and is a member of the FB world.
Keep in mind, replay will take as long as it takes for him to get through it. As I have mentioned before, your h is a very slow one and as time goes on, you will see more changes taking place. The person you knew is no longer that person. He is growing, experimenting and trying to figure out who he wants to be when he grows up. Eventually, the behaviors will settle down, but it will take some time.
Nothing they say or do surprises me these days.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
