Sometimes they leave their belongings to have an excuse to return periodically to get something, other times it is for a connection, but the one that always stands out for me is that everything he has left behind are reminders of his past life and just like an onion, he has peeled the old layer away and does not want the reminders right now.

If the clothes, etc., are disturbing you, pack them up and place them in the closet, attic or basement. Some day, he may want them, but I seriously doubt that he does right now.

Your h said on of the right words about coming home, etc., but he's not ready to take the plunge of stepping over the threshhold and coming home.

I'm sorry to hear about the situation with your parents. It's tough when they are ill. I hope and pray that they will be better very soon. If you are in no hurry for the divorce, then don't file just yet. Put your focus on your family and on you for now. It sounds like God is trying to point you in the direction of your parents right now.

Pleae take care of yourself.

Sit quietly, the answers will reveal themselves when you least expect them to.
The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
