Even the Catholic Church will make an exception for this; at least, it did for my cousin and that was at least 20 years ago. My cousin's husband was a dedicated alcoholic and was not interested in being helped. She went to her parish priest and he told her to divorce him. I remember my father said, "boy, priests have changed since I was young".
She divorced him, and eventually found a nice guy and they have been married for a long time. I don't think there is anyone, anymore, who insists that a woman should stay with a man who is a serial adulterer, or an alcoholic who refuses help, or a drug addict.
The point is this article makes no such exception
But most divorces are not about that.
Mostly they are about people not wanting to put in the effort to stay married. There might be some work involved or they might have to (gasp!) actually change a habit or two.
Marriage is about putting someone else's needs above your own wants. It is not for the weak or faint of heart.
