“Infidelity on the part of a husband or wife is not a reason to erase one’s marital vows.”
I think Jesus would disagree with the author:
Matthew 5:32
But I say unto you, That whosoever shall put away his wife, saving for the cause of fornication, causeth her to commit adultery
That’s the ONE thing you can split the sheets over
Quite a bit different than the Catholic NAB;
"But I say to you, whoever divorces his wife (unless the marriage is unlawful) causes her to commit adultery, and whoever marries a divorced woman commits adultery."
