I’m not exactly sure what your response means.
But I think it’s always a good, Christian response to feel sorry for someone who has made a huge mistake. (’But for the grace of God...’)
Someday you will make one - if you haven’t made numerous ones already.
We are all sinners. I’m a wretch like the rest of us.
But to say “I am sorry, truly, for the pain you are in.” That implies that Regretful’s pain is worthy of sorrow.
Not all pain is equal...the pain a mother feels in a miscarriage and the pain a parent experiences when burying a child is one level of pain. Those are pains borne out of innocence, through no fault of the experience owner.
If Jane had cut the tacit blaming of society for Regretful’s actions in the first few paragraphs, and started at “The thing is, Regretful, marriage very quickly loses the romance...” it’d be better.
That said, I agree....Jane gave good advice.
