In the same way, a woman who divorces her husband and marries another man commits adultery.”
But now I tell you: if a man divorces his wife for any cause other than her unfaithfulness, then he is guilty of making her commit adultery if she marries again; and the man who marries her commits adultery also.
but if she does, she must remain single or else be reconciled to her husband; and a husband must not divorce his wife.
And if a Christian woman is married to a man who is an unbeliever and he agrees to go on living with her, she must not divorce him.
