I think as painful as it is you have to let it go. You want answers and I understand that but sometimes you can't have answers. You have to allow the Order to act as closure. He for some reason is saying loud and clear that he isn't giving them to you. I would donate the clothes and walk away. What you see as getting information he sees as violating his space. He has made that clear. This Order says that he wants to take the coward's way out. And that is his right. Accept this as his bold statement. Maybe later he will allow you to understand the choices he made. I wouldn't involve the courts yourself or take this any further. They are still his things and he apparently doesn't care about them. At some point you have to practice acceptance even if it makes no sense.
