Bea, I had to chuckle about the birth notice. Many times, especially during the holidays, the mlcers will make come out of their hiding places and touch base. I suspect that your xh is doing this. He may have had a moment of clarity and decided to let you know about the addition to his side of the family. He's just sending you a little post card from Mars. It's just a blip on the radar.
Bea, I truly understand how you feel....
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.
