It’s really nice you reconnected with your friend and gave her a shoulder to lean on.
H’s text blaming you for how the kids are reacting to him, was handle beautiful. Let him be. Let him stew in what he crafted. S22 and D20 are adults and can express their feelings to Dad how they wish. Their relationship is just that - their’s; H is just trying to bring you into the middle of it. A no response was perfect. Of course you know you can guide your kids a little, if and when it is asked for, or needed. You know the power of compassion and kindness for one’s self. The kid’s emotions will settle and they can walk the better and not bitter path, like their strong Mom.
Sorry D20 is having a difficult time. This is a lot to take in, a lot to process. Glad she is reaching out to you.
I’ll be thinking about you while you are at the meeting with lawyer. I hope it goes well.

Feelings are fleeting. Be better, not bitter. Love the person, forgive the sin.
