Help! Need advice- am I wrong?

Ok I'll try to be brief here- I just need some support and advice.

So my husband has to periodically go to Florida for work. He last went in June and extended his stay to go visit his parents for a couple nights since they are just an hour or so away from where he goes for work.

He had drove down and was about an hour into his trip coming back home when he called me and said he forgot his wedding ring and is pretty sure where he left it(at their house). He asks if I want him to go back and so I tell him not to as it would add at least 2 hrs onto his trip home. I then told him to call and make sure its there and to have them hold it and we will get it the next time we see them.(we usually visit as a family a few times a year or they come to our place). I adamantly told him Do Not have them mail it to which he agreed. I don't trust the postal system and esp with something that can't be replaced and you can't really put a value on.

He later calls and confirms its there and tells his mom not to mail it. Ok great news!

Wrong- his dad calls him and tells him he mailed it- my husband tells him not to do that and he says it already picked up and we will have it that monday(this is on a sat).It never came. Its been a month and a half. Its been been reported missing, we have spoken to different depts from USPS and all cases have been closed. His dad recently got the pathetic $100 of claimed insurance on it.

Ok- now heres where I need help. I'm beyond upset over this. Lost sleep, have had anxiety, and the emotions of an empty mailbox.

I'm so disgusted that they disrespected our wishes to keep the ring there. And they never have spoke to me or apologized to me. My husband thinks I shouldn't cut them off and that I shouldn't hold on to this and its been really hard on our relationship as I've told him I don't see myself getting over this or speaking to them anytime soon. I understand his side and they have apologized to him and offered him $ to buy a new ring.

I feel disrespected that they have not personally apologized to me. This has greatly affected me and you can't just replace the ring- it will never be the same. You can't put a value on it. Our 13 th anniversary is next month too.

What do you think- am I owed and apology too? Should I try to let it go-

Just looking for how others would feel in my place and what to do?

Thanks!
