DH cannot stop throwing other peoples' things away

[Gangle]

This is only one of many issues we have in our relationship but DH continually throws away other peoples' possessions, mine mainly because we live together but when he goes to stay with his mum or dad, he does the same to them. Items he has thrown away include cheque books (unshredded and in date), our household insurance policy, the Sunday papers (on Sunday evening, before I have read them), any food he doesn't like the look of, unopened (brand new) packets of envelopes, my shopping lists, a diary I was keeping about DS, 7 months; I could go on . . . Once, because he bins all our bills/payslips/invoices of any kind (paid or otherwise), I reordered our council tax bill as I needed it to apply for a parking permit. It arrived, he got to the post before I did and binned it. I ordered another copy but, again, he got to the post before me and binned it. I should also add that this happened over the time I gave birth so, 3 days after a c-section, I found myself walking in the pouring rain to get to a solicitor's office to swear a stat dec to enable me to get a parking permit so that I could park my car near where we live, all because DH can't stop throwing things away (I should also add that I racked up two tickets of £60 each in the interim). Funnily enough, he doesn't chuck his own stuff out; there are piles of papers and his rubbish all over the house which I don't touch because I can't deal with the cr*p that follows (he got very angry once when I chucked out his Times Literary Supplement in retaliation for him throwing away my (unread) copy of Hello magazine)). He has admitted he has a problem but seems unable to stop it. We saw a relationship counsellor who said, interestingly, that it was rather like a dog marking his territory, i.e DH is staking out his territory by chucking out anything that isn't his. He comes home and immediately starts looking around for something to throw away and won't rest until he has found it. It sounds funny but it has now got to the point where, despite all our other problems, I cannot live with someone who has no respect for me or my possessions. Just to add, I am extremely tidy and the house is about as minimalist as you can get! Can anyone help?

Has he seen a GP or does he not regard it as problematic?

He sounds obsessive compulsive and like he needs help.

I was just going to say OCD as well. Some cognitive behavioural therapy might help?

I wonder if you could agree to a box with a lid on that he JUST does not open.

It is a bit of an issue- on a lighter note my dh is similar but if he leaves something on the dining room table its there cos its important if i leave something he bins it cos it must be rubbish.

My dh sounds similar, I am forever getting things out of the bin. I make him get the things out now, and would generally make sure that he paid the price if his binning something cost money or caused inconvenience and it seems to help, with my dh it is a kind of impulsive tidying thing, and he just wants things out of sight, and if the bin is the closest thing, that's where the offending thing will be put.
No answers I'm afraid, although, my deepest sympathies. More relationship counselling, or maybe he should see a therapist alone, that may be more help. DH used to, but doesn't anymore, I know he was more respectful and a better partner when he was still seeing someone.
The only practical thing I can come up with is, maybe you could get a big box for his stuff, then he can file/bin/sort it in his own time, and you don't have to live in your minimalist sanctuary with reminders of his territory marki8ng habits all over the place

Nothing would please DH more than if I got a big box full of my stuff that he could bin all in one go. I can almost see the glee in his face if he were to come across it. My mum suggested a safe or a padlock. Is it wrong to start binning his stuff to get even?
