I remember HRM's husband having the traveling toothbrush in the bathroom. If I recall, she moved it few times and he would put it back where he had it. Finally, she just left it alone. We got a good laugh out of that toothbrush activity. Her h never left home the entire time and acted out, but they finally made it through the rough times.
Clothes moving back home? It may be a sign that he's slowly thinking of returning home. But I would not put much stock into my comment until you've seen more activity w/the movement of other items back home. Whatever you do, do not call attention to the clothes. Stay calm and observe.
Continue as you have been. I think you've been doing great. Keep up the good work.
