The begining of the rest of my new life? (3)

[Ripe]

STBXW just forwarded me an email from S9 teacher.
Last Friday they sat down in class and shared their problems. S9 shared with their colleagues that mom and dad live in different houses. Because of this, another colleague found the courage to announce their parents were also separated.
My S9 got up, crossed the room and hugged his colleague.
STBXW is proud of S9 and says his gesture tells a lot about him.
I really don't know what to tell her.
I would like to reply:
"Dear STBXW,
S9 really has a heart the size of the world. He is an emotionally intelligent person, as we both know. It saddens me, though, that our separation is a topic of our son's sharing. I am sorry you don't share this view and just keep saying that kids are resilient and can endure everything; that our kids are not the first and will not be the last with divorced parents. It saddens me deeply that they don't have and will never have again a family. Shame on you for this email."
