ANSWER:

She must not obey her husband in this and must not send her children as this person is a soothsayer and a sorcerer and this will affect the kids with jinn possession. She must tell his parents and her parents about this to talk to him as this is shirk. If he doesn’t stop and repent to Allah, she must leave him.
