Time tends to fly around here. So, he contacted your son via Facebook....sounds like he can't take a chance on calling him for fear of being rejected by your son. I do hope your X is pleasant to your son at tea.
Mandy, your pod wearer will eventually contact you. They always do touch base at some point. I'm very happy to see you are living your life to the fullest and that your son is doing well.
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.
