WR, I'm very happy for your son. This was a huge step for him and I'm proud of him and I don't even know him. Congratulations to your son. I know you are very proud of him and will be there for him no matter what.
Also, congratulations on having some work come your way now. I'm sure you could use the money and the time to focus on other things.
Trust your gut on whether or not you respond back to him...but if you do, wait a couple of days before doing so and respond back w/a question..."H, what do you think you are missing? I gave you what you requested." Leave it at that. Don't offer up anything more. If I recall, you did have a discussion w/him a while back about clothing, i.e., ties and that you were keeping a few for your son. Whatever you do, don't get into a text battle w/him.
To be honest w/you WR, I think your h is going to be a problem child and he and his family are going to continue to bug the crap out of you for a while. If your h continues to ask for things from the home, set a boundary and put a stop to giving him things. I insisted on a list from my xh be provided to my lawyer and I would review the listing and give him what I thought was proper. He still went back and continued to say he had personal items in the home, which he didn't and thank goodness I had his list and took photos of the things I gave him. You may end up having to do this at some point...
If you don't want to respond back to him, then don't. He needs to understand that you don't own a storage facility and since he's not been back to request additional items, you very well could have assumed that he didn't want or need them and gave them to Goodwill. Anything is possible when it's been 8-9 months of disconnect in communication. LOL!
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.
