They are not just unwilling to change. They are unable to change. They will never change.

Anyone hanging in there, going low contact and hoping for change will be forever disappointed.

Another reason to go no contact is because going low contact can still offer them opportunities to infect you with their toxicity. You might think that you're an adult now and therefore beyond their ability to cause further emotional damage, but that simply may not be the case. Of course, their toxicity and its effect on others differs from individual to individual.

As for me, I've gone low contact my entire adult life. I'm now 60 and my parents are in their eighties. And for me, one significant benefit of going low contact is that I see how they've diminished -- both physically and in importance -- over the decades. They're no longer the larger-than-life figures of my childhood; they're now a couple of sad old people who have no power over me whatsoever.

However, other than that one benefit, my continued contact with them hasn't benefited me in any other way, nor has it brought any additional joy to my life. And when I do contact them, I afterward feel like I need to decompress. There's still some stress involved and always will be.

If I were to do it all over again, I'd probably just go no contact. It would be easier in many ways, and even the little time and energy I spent on them could still be better used elsewhere.
