If someone got married then yes the hope was that a Bayis Ne’eman would be built.
Of course there are times, exceptions not even close to the amount that are bandied about now-a-days that one spouse failed in thier duties due to an inability to conquer or change thier middos in what ever respect and therfore a divorce was needed.
However that in no way diminishes the fact that it is tragic that the home was broken.
