As far as I'm concerned, making your family live in a hoard is as selfish and damaging as that. I couldn't stay
If the relationship were on an equal footing, spouse to spouse, then to some extent, neither would anybody else.
But it doesn't appear to work like that all that often. A dependance creeps in. As a teenager I felt responsible for my mother, for containing the hoard, for slowing down the incoming, speeding up the outgoing, and hiding it. The hiding it was important. To save her from judgement, shame and legal consequences.
I've seen that replicated in couple relationships. Where the non hoarding spouse overtime becomes worn out from the inexorable overtaking of their life on so many levels, and they become the gatekeeper, the White Knight, the smoother, the last defence against being found dead buried under collapsed piles of crap, or a smouldering corpse that was once somebody you loved who had no hope of escape when a fire broke out.
And unlike other addictions there isn't the same social sanction as there is for alcohol, gambling or drug addictions. There is a very real pressure externally to "sort it out", "get him/her help", "deal with the hoard". Walking away, as I have learned, can cause as much damage to your self image as staying. Becuase having spent so long feeling responsible, you have no defence stratagy when the hoard leaks to the point of visible and the world and its mother looks at you askance saying "how could you let him/her live like that ?".
Parents I think have a worse dilemma to deal with than I did. Becuase their children will likely be exposed to the hoard and its associated behavoirs without their "non hoarder" presense in terms of limit setting and brake power.
Or social services will intervene and the children won't be allowed in the hoarding parent's home causing them very real grief. Becuase they aren't stupid. They see a parent drowning, it looks like nobody is helping and they can take that on their own shoulders emotionally, if not physically.
And the truth, they aren't wrong. Nobody is helping. Leave a gambler, an addict of drink or drugs and you can push for help and services to be sent their way.
The help for hoarders is very very limited. The people who love them are often the only defence against them actually drowning (to the point of life changing injury or death) in their stuff.
It's not easy to walk away under those circumstances.
And even if you do, it's not over.
I feel like Damacles' sword is hanging over my head. Just waiting for the day she is found buried under The Hoard 2.0, and the entire commenting public on the Daily Mail et al sucks their teeth and judges me a heartless selfish bitch on wheels. And I'll believe them. Becuase a large part of me thinks they are right.
