He doesn't get it

Chris and I are more different than we are alike.  We have lots in common and when it comes to the big things (life goals, parenting, discipline) we're completely on the same page.  But we're different in quite a few ways, too  He stresses about stuff, I don't.  He has everything completely organized, I don't.  He thinks being five minutes late to a function is ok, I don't.  Oh, this is fun.  I could go on and on.  The most important thing is that we work really well together in all the ways that matter.  We're an awesome team.  BUT... he doesn't understand some really important things about me.  Even after 15 years.  Like it completely baffles him that I have 4 bureau drawers full of sweaters.  He thinks I need one, maybe two.  He doesn't understand the bookcase full of books that I've already read.  Who buys books, reads them, then rids themselves of them right away?  What if you want to reread it?  Or reference it?  Or loan it to someone someday?  

I did some spring cleaning today and in addition to all three kids' closets, I went through my own.  I also chose some books to donate to the library.  I could only part with a handful.  I told him emotionally I just wasn't prepared to part with more.  He just blinked at me.  Then I tried to explain that earlier in the day I got rid of 3 sweaters I hadn't worn in a few years as well as all my favorite clothes of William's that just don't fit him anymore.  I swear it was like I'd started speaking a different language at that point.  Becoming emotionally attached to material items is not something he understands and I would say it's one of my biggest faults.  Then to evoke some sympathy I said, "I even had to pack up the outfit William wore on his first day of preschool because it doesn't fit anymore!"  and he looked at me like this: 

It was clear the conversation was over.  He doesn't get it.  I'll just feel sorry for him for it 'cause loving sweaters and books and first-day-of-school-outfits just makes you feel good.  Don't you think?
