This sounds like a space problem as much as he feels for you maybe to much for him and his therefore not ready to settle I would back off collect your things by demanding them back then go silent no texting or phone calls just silence Don't let him think your there everything this happens let him hae to work for your attention then you will either move on or he will swoon to your attentions

When people do this kind of thing and aren't willing to speak with you about what they're feeling you can only go by their actions. And his actions are telling you he doesn't want to be in a relationship, and that he doesn't hold enough regard or respect for you to let you know to your face.
I'd forget about the belongings, take the time to heal from his dismissal and move on with your life
