Otherwise, H will think that you've been filling D6's head and feeding into her insecurities. Then he'll target his annoyance and anger to you for "setting" up H. Tread carefully, dear Busting.
Busting, I just wanted to second what Wonka has advised.
This has been my experience every time i've tried to initiate conversations about the kids' hurt with H.
He is now adamant that I've poisoned the kids against him, and that I am the reason they no longer want to go anywhere with him.
