Wendy, When my xh walked out, he took only the clothes that he required for work and a couple of casual outfits. My mother and I spent one entire night packing up his stuff and placing all of it in our detached garage. I sent him an email at 1 in the morning and advised him that he needed to come and pick up his belongings as soon as possible. It took him several trips to just get his clothes and things of that nature. After I had contacted a lawyer and had a draft separation written up to xh's specification, that's when it hit him that he wanted other things such as his baby/childhood photos, my key to his blazer and yes, the infamous plastic easter egg. When he finally came to my home with two deputies, I had a whole lot more stuff for him to take because he was not going to get another chance to come back into the residence. He was even asking for things that he had tossed out or donated to Good Will. The deputies thought he was nuts and he sure put on the nutty appearance for them.
Whether you pack the stuff up and put it somewhere or toss it, I can almost guarantee that he will be asking for stuff 1, 2 and even 13 years down the road. My xh periodically still asks for things and I advise him to go back and read his divorce decree. They are truly nuts and don't have any concept of time and what the consequences of their actions create not only for us, but them as well.
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.
