Inferences are interesting. But not conclusive, especially when there are clear passages which speak about divorce and remarriage.
For example, such as:
"For the woman which hath an husband is bound by the law to her husband so long as he liveth; but if the husband be dead, she is loosed from the law of her husband. So then if, while her husband liveth, she be married to another man, she shall be called an adulteress: but if her husband be dead, she is free from that law; so that she is no adulteress, though she be married to another man" (Rom. 7:2-3)
For example, such as:
"For the woman which hath an husband is bound by the law to her husband so long as he liveth; but if the husband be dead, she is loosed from the law of her husband. So then if, while her husband liveth, she be married to another man, she shall be called an adulteress: but if her husband be dead, she is free from that law; so that she is no adulteress, though she be married to another man" (Rom. 7:2-3)
Divorced people don't have husbands [or wives]. So this has to be talking about separation/abandonment instead. Jesus proves that in his discussion with the Samaritan woman.
John 4:17: The woman answered him, “I have no husband.” Jesus said to her, “You are right in saying, ‘I have no husband’; 18for you have had five husbands, and the one you now have is not your husband. What you have said is true.”
