Hi Casey Have all his things assembled in one place protected of course and photogenic evidence they are not damaged. Send him a copy nicely letting him know the items are to be picked up.
A second option would be to put all this things in a location and keep them there if they are not in the way. Is there a location where you could do that without his items being inside his house.
Usually this is done after legal proceedings or a mutual agreement in the US.
When he is getting his things it is an emotionally charged time. Do not be alone then.
