I suspect that there are issues being mixed here, and this provokes some to make rash statements or generalize beyond what is realistic.
That families sometimes mingle and interfere in the lives of a young couple is ancient history. Certainly they can be supportive. Sadly, they are too often a significant source of negative energy. What might even be a legitimate conflict can easily get amplified into something horrific. Resolving that is much harder.
When a couple is feuding, it is quite common that their respective families choose sides. While understandable, it is most often disastrous. Instead of a conflict involving two individuals, it can deteriorate into the “Hatfields and the McCoys”, and degenerate into families becoming enemies with little reason to dislike each other.
The get refusal issue has been blown up greater that its real size. No, I do not deny that there are couples out there who should have been divorced by gett long ago, and are still not. And the generalized statements pointing to evil men and evil women are foolish. The greatest majority of gittin not being given yet are because of the difficulties in working out agreements to settle the affairs of financial support, custody and visitation, and related matters of the divorce. In this huge category, there are holdouts, both the men and the women, who are recalcitrant in the progress towards an agreement. And who is right or wrong is not established by statistics or by generalization. No two cases are the same.
Those cases that end up in court (often with halachic approval), tend to drag on longer. There are get refusers who choose to abuse their wives by withholding. There are also many who are given this refuser label unfairly. I have encountered women who make unrealistic demands, and threaten to make false police reports of abuse against them and/or the children. Others have stated openly that they will put out rumors of get refusal. Until hearing both sides, it is unwise and unfair to reach any conclusion about any individual case.
