Just that really. I found out from FB that my ex got remarried a couple of weeks ago. Our kids are 13 and 8. He hasn't seen them since last December and hadn't answered any messages from me since February. They don't want any contact with him bc he hurt the youngest last time he saw them.
I have no idea if/when/what I should tell them. I think they might be upset if they found out that I had known and not told them, but maybe I should keep schtum.
