Abba, the reason he doesn’t want to divorce her is because he likes her and wishes to remain with her and, yes, put up with her indefinitely. Just as they both agreed to do when they both agreed to marry each other.
Person1, your comment is entirely inaccurate. I am very much interested in how the Torah relates to our lives, including in the topic at hand, and my comments very much reflect that.
When someone cites Shulchan Aruch or contemporary psak halacha from the posek hador, that precisely *is* guidance from the Torah on how to live our lives today.
