Parents (especially mothers) try to alienate the children from their father.
My parents had a very messy divorce about thirty years ago. There was lots of fighting and the fact that my mother became frum during the process (and my father didn’t) added much more stress to the situation. But in the end, my mother went to great pains to make sure that she wasn’t putting down my father in front of my sister and I.
In the end, I did become alienated from my father for a while, but it was pretty much my own doing. Even while going through the divorce process, she would every now and again try to convince me to end my estrangement from my father.
My father and I did end up reconciling when he remarried a few years later. Oddly enough, my mother and step-mother are now very close, and my parents have long since evolved to the point where they can be friends.
