whooops..well there is a gene identified with hoarding. not to burst your epiphany bubble but getting him to change won't be easy from what i've researched on the topic. number of other dx's come with this behavior. it's often times "arrives" after a great loss in the person's life. but then it becomes more than that. oh dear....hope he's willing to let you throw out things or give away.

...and By Mayo Clinic staff
"It's not clear what causes hoarding. Some researchers believe that hoarding occurs on a continuum — some people may simply be considered harmless pack rats, while others have a much more severe form of collecting that is life-threatening. The condition is more likely to affect those with a family history of hoarding, so genetics and upbringing are likely among the triggering factors."
let us know how it goes... meantime bon appetit, chef!
