You beating her up, in this case by throwing your son's picture in her face, is not going to shake her out of the denial. I can't help but think the kids are getting some of these vibes or ideas from you, and that you kinda like that your son did this to show her how wrong she is.
"Look W, you're hurting the kids! Come back!" That's the message I got. So you're trying to guilt her back and control the situation.
