Yes, I did read the gray rock theory, that's what I'm trying to do.

I donated a lot of his stuff to goodwill and put most of his furniture in a consignment store. I am just keeping for him the few things he asked for - his bedroom set and nice television, a few nice clothes. I'm happy to do that for him, as when he does move back out on his own he will have a nice bedroom and that will mean a lot to him. Getting rid of it now would be spiteful and likely to trigger a lasting grudge, which I DON'T want.
