Hello my friend. Happy Anniversary. It is still a day worth remembering.
And congrats to your son and his girl. Such happy news.
I agree with BMF, there is so much info out there and somewhere he is associated with your name.
As far as whether the news of the engagement will set him back, I am guessing it wont. Even though he is still stuck in the tunnel, I am thinking he is far enough out to realize that time is moving on.
My hope for you, my friend, is that he continues to reconnect with his children and that you and he one day have whatever kind of relationship will give you peace.
