This is Dr Nyland’s note:

“Husband of one wife” is not a correct translation. The Greek is a stock phrase which referred to women as well as to men and meant “faithful to one’s partner”. This has been clearly demonstrated by inscriptional evidence of the times. The phrase was often written on women’s tombs. A list of references for where this phrase (as well as its Latin equivalent) appears for women can be found in C. Keener’s book,And Marries Another.
