my hubby started to go thru his stuff also to "reorganize" or keeps his things "safe" and got me very frustrated as well. This was 3 years into his diagnosis. He didn't want anyone to take his stuff either. And it was mostly HIS stuff that he would do this with. At first, he wouldn't let me have anything to do with his stuff, like put it away or move it, etc., once he started to "see" what he had and what to do with it. He would voice his frustrations to me and say things like "THATS MINE!" and I'd always remind him that "yes, it IS yours" but i'm just gonna move it over here cuz I need this space for a minute" and he'd almost always be okay with that and he'd go onto something else. I realized at the end of the day as long as he wasn't hurting anyone or anything and it was something he enjoyed, I'd let him have that. Because it wasn't long before he lost interest in "reorganizing or keeping things safe" and he would focus on something else, and once i got him into bed I would roam the house and see what really needed to be put back in place or just leave it alone. He was like a kid who was curious about things, whether they were his or someone else's. So the one thing I HAD to do was lock up our meds so there would be no accidents. It was about this same time that I took over his medication regimen. I also locked up anything else I didn't want him messing with and if he couldn't get the cupboard or drawer open, he would just move on and not really question it. You may have caught on that i'm talking about this AND him in the past tense, because yes, he is no longer here. He passed away not too long ago and just wanted to share a little of my experience about this and what helped me get thru some of my challenging days. I give hugs to all you who are struggling with this... just remember patience because your loved one didn't ask for any of this and he can't control some of the things he does, Whether it makes sense or not.
Love,Strength an Peace
