Did you ask him where this somewhere else might be? In a conversation with my XH last summer, he said something similar about moving out of his current place.
I asked him, "Where are you going?" He said, "Home, if that's still a possibility." I told him it was, but that we needed to talk more about it. Well, that's as far as it went. He didn't bring it up again until a couple of weeks ago and basically in the same way.
My point is that I think my XH really had no intention of moving home then or perhaps, even now, but wondered if it was still a possibility. Maybe your H is trying to feel you out. Or maybe not--you just never know.
Don't spend too much time trying to figure it out. Just try and enjoy the day--it's Friday. YIPPEE!!
