I think you need to dig deeper to find out why exactly that bugged you so much.
Maybe it was a good sign. He wants to finish something he started.Maybe he is picking up the pieces of his life, starting with his star wars model.
He probably put off contacting you for them.because he feared a bad reaction, which he got. This ocuring repeatedly will deter future contact.
I am sure it isn't easy. Though if you figure out what exactly you reacted to you could understand yourself better too.
If you want more and were disappointed you need to lower those expectations and hopes. If you want the rest of his stuff gone, let him know that. Only you can identify the true trigger, but I think it is important to try. Ask yourself why I feel/think this way. Then with each answer reask until you get to the core reason.
I get you are not happy with your situation. Understandable. However I also hear judgement in your words. Stop judging him. Especially about what he is doing now. It should no longer bother you. Him having the time of his life or a lot of spare time is at best speculation. Don't mindread or speculate. You create stories in your head that influence your thinking and these could be the opposite of his reality. Doing so will not benefit you.
Plus before realising that things weren't so bad before, often the WAS must experience that it isn't so great afterwards either. So it is actually good that he isn't living it up.
Depressed people would not have the interest nor the ability to do a model. Again a good sign.
Best wishes
nice post Roist!
Coly it's been a while. Just wanted to check in and see how you were doing. I think there is a lot there for you to digest in Roist's post. Hope you have a nice weekend!
