I thought that was a more interesting question!

"I wonder how many married men would have agreed to marry their wives if she told him in advance that she would never, ever have sex with him, even after they were married."
I would have. I would have been heartily disappointed in some ways but the chance to spend my life with my wife far outweighs the delights of sex.
That's how much I love her. I would be willing to give up even that. Sometimes that's not always a choice. If there was an accident, or something happened that physically prevented sex, that would in no way mean I'd see the relationship as over. It would just mean living the life as it was handed to me, and being the better person for walking with her throughout my life.
As far as the article goes, of course he should break up with her. Unless he's on the same page spiritually they will run into problems no matter what. Good for her that she's taking a step to find more wholeness and inner peace, and it'll be better for her to get away from this guy and find someone who is a much better match.
