Becky, I have several thoughts on your h coming to get his "stuff".
1. If you think you can hold it together, then be there, but stay in another part of the house. Leave him to removing his stuff.
2. If you do plan to be there and don't feel comfortable facing him alone, then have a friend come over and keep you company.
3. If you would prefer to not be there, make sure you have put all of your papers and things of value in a safe place, just in case he decides to nose around while unsupervised. (Don't ever assume that he will just come and get his stuff...they tend to take things that you may not notice right away.)
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.
