What is the religious ruling on a father who does not provide for his children and wife, corrupts his young son, engages in illicit relationships, and refuses advice? What is the ruling on the dealings between him and his children and wife?

This father has wronged himself by neglecting his trust and failing to provide for his family, spending money instead on forbidden things. His family's duty is to advise and admonish him gently and kindly, to disobey him in matters Allah has forbidden, and to strive for his reform. If advice is ineffective and he has a negative influence on the children, we advise separating from him if possible, especially since he does not provide for them.
