Hi SeekingHelpNow,
Welcome to the forum and thank you for sharing about what’s going on for you at the moment.
It’s never easy explaining the reasons for a divorce to children but so much harder when the reason is something like sexual abuse. I think you might find this reply to a recent post helpful: Help, talking to children and leaving.
Hopefully some of the other forum users have insights that they can share too.
Take care and keep posting,
Lisa
