I don’t know what the view of the Eastern Orthodox is on marriage, (though I find most of the rest of their theology to be vapid) but on marriage the translation is indeed correct wherein it says that a man should not put away his wife, except for the cause of fornication. This might be the same in other places where it speaks of one spouse abandoning the other. Though even this separation (for adultery on the part of one spouse) is a terrible and foul thing, since He also says “what God hath joined, let man not cut asunder.”
Though, since we are not under the law, but are in fact “dead to the law by the body of Christ; that ye should be married to another, even to him who is raised from the dead, that we should bring forth fruit unto God” (Rom 7:4), I would say that any guilt over separation under such circumstances, and any notion of only getting a “second” chance, or even a third or fourth, are absolutely absurd in the presence of the forgiving God.
