Also, her plea that the LC is her oxygen and so she needs it as much as possible is
selfish malarkey. God will meet her "oxygen" needs in the faithful carrying out of her spousal obligations. That's precisely how God does things. Paul was in prison and testified that God was meeting all his needs (Philippians ch. 1-4.)
Ask her, if she had children, would she neglect
them to get her "oxygen" needs met? How self-centered! How lacking in understanding of how God really works.
