Ubiq -“If the marriage is over, to be a mencth a get should be given”
Nothing to do with being a Mentch. If it’s really over, it’s a big Aveirah to withold the Get!
OTOH, either the man or the wife, if one of them thinks that in our generation, that marriage is temporary – then –
This shouldn’t be tolerated.
The only way to figure this out – for the couple to go to a Non – biased Therapist!
