Douey Rheims:
And I say to you, that whosoever shall put away his wife, except it be for fornication, and shall marry another, committeth adultery: and he that shall marry her that is put away, committeth adultery.
Note in D/R says as follows: “Except it be”: In the case of fornication, that is, of adultery, the wife may be put away: but even then the husband cannot marry another as long as the wife is living.
Yes, the hubby can remarry in the event of an unfaithful spouse and it not be adultery.
