Having been away from them all for over a year now, it is much easier to stand back from my 'mother she bear protective side' and just listen. And if I can't externalize something for them, so be it.
That's great that your doing that! Listening is super duper important.
If they feel hurt because of their father, that would be a perfect time to listen, hear, acknowledge, and talk a bit about your family (any that were a normal relationship) because they will later think about that and
if he did hurt them, they arent likely to go back and tell him.
I say "if" in italics because being fully "brainwashed", there is no "hurt by" because it all gets reasoned out as justified because i was bad or did bad or made him do XYZ because i did ABC. Etc. So there may not be a time where they feel hurt BUT there may be a time their
should feel hurt and if you can zero in on that and say (id say it would work even if its a lie as long as they didnt know better...didnt know this family member or a pretend friend) "well I was hurt when my aunt did XYZ" or whomever. It can help them see that not feeling hurt isnt normal.
Does any of that make sense? Certianly you cant act like a therapist or anything but there are subtle things you can say that can make a huge difference. And it seems you are doing that and its great.
A horse looking for the opening, I think that's what this is about. You can talk about normal relationships you've had that shows them that this isnt normal (all without putting him down) and it will shows them that the opening isnt here but its behind them and help them to turn around, you know? Its not about "putting pressure on" but rather "this isnt normal" but maybe its the same thing.
