Speaking about the second husband divorcing his previously married wife, they can come back together if they wish makes sense.

If we take this to mean that after 3 genuine divorces you are never allowed to marry again seems to me a bit too far as marriage and divorce are not crimes and even these have forgiveness, so I take on board what is said but still consider marriage to first husband an option as marrying someone else may have taught them a lesson.

If anyone has been married four times or more, it takes a brave or stupid person to try and be the fifth!
