Divorce parents and children of divorced parents, what was done right? What was done wrong?

My divorce will be final by the end of this month and he has moved out. Obviously my first concern is my kids. We are being honest about what has happened and have kept up a dialog with them about how this will impact them. We’ve also been very clear that this is not their fault. They are 10, 9, and 6 and I would be very interested to hear stories from children of divorced parents or parents who’ve been through this with their own kids.
