WR, I hope that you are planning something special for your son.
I'm not surprised to read that your h is unfriending your family and friends...it's typical mlc behavior. He's following the mlc "how to book".
Hang in there.
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.
