It's autumn. A time of reflection. The busy harvest time is through and winter is coming.
We changed the clocks about a month ago and that's an energy sapper for me. The light changes and I get in hibernation mode, and my energy slumps. So I can relate to your feelings.
Now, about that dh of yours. You each need your own space. Quilting is hard enough when we have our own stash, UFOs, WIPs, and current stuff to keep straight. Color coded bins might help keep your stuff separate. Maybe you and he could go on a shopping trip. That might get you outta that slump.
