O.K., I'm laughing right along with you guys here...in my apt. after the marital home I had a closet SO BIG it was like a little room! I kept the kitty boxes in there and had room to stand up straight under all the shelves. It was heaven!
I'm glad you have a patio for flowers and such. I really missed that when I was in the apt.
I also think you are dealing with your son perfectly by letting him be whatever part of moving that he wants to be.
FWIW, your H's L sounds like a real piece of work and I don't think his antics will be beneficial. Nobody, including a judge respects a big blow hard. Kudo's on your L selection.
