Want to know the scenario I have seen the most? Some uncomfortable, shallow relationship persists because cutting out the toxic parent means cutting out the rest of the family. Other family members insist that they ignore the jabs and small offenses because nothing is more important than faaaaaammmmmilllly. Sometimes those pleas work and the corpse of their relationship shambles on like the Walking Dead. Other times they give up and just go away. Both outcomes are similar, one just has fewer chairs at Thanksgiving.It doesn't always happen. But I have seen over and over a person's personal political beliefs--that are entirely hypothetical--crumble in the face of the reality of the impact those hypothetical beliefs have on their own children. When it's happening to someone else, it's easy to spout nonsense. When it's happening to those we know and love, it can be transformative. Not always, some are so consumed by hate that they cannot be redeemed even by their own children.
I haven't seen many situations with open, explosive hate. I haven't seen grand transformations where everyone hugs it out. I've seen plenty of claims that love would have conquered all if only the child would have stuck around to realize it. I have seen children just decide it isn't worth the trouble. And while I don't have nearly enough information to say with any kind of certainty what is going to happen here, the small bit I've seen reeks of a nice, quiet estrangement in the future.
