<human>: I'm 28, he's 29, together 9 years.

Just after we got engaged, his father told me "I need to give you [husband's mother's] engagement ring! You don't have to wear it, since you have your own, but I still want you to have it."

I was VERY honored and said "I would definitely wear it with my own ring." A few months went by and nothing happened so I assumed his father couldn't bear to part with it. A-OK. I wasn't going to push.

Well, this week he's on a business trip. So I was doing laundry in his absence and went to shove stuff in his underwear drawer. I felt towards the back a hard object.

I pulled out a black sock that had a ring box in it. Inside was what I can only assume is his mother's ring.

So his dad DID give it to him. This had to have been almost 2 years ago. Why would he hide it? Why wouldn't he give it to me?

I know it's his late mom's ring so there's probably a lot of feelings there. But I've lost a parent too so I'm not blind to the idea. In fact, I gave him my late father's watch.

So why wouldn't he want me to have it? I love jewelry, he knows I'd wear it. Is it that he doesn't feel I'm worthy of his mom's ring, or is he planning to give it to me at another time?

For a couple that doesn't hide much this feels weird and uncomfortable to me. And where do I go from here? Pretend I never found it, or bring it up?

Provide a brief overview of the text.
<bot>: Normally very open husband hid the fact that his dad gave him his late mother's engagement ring. Why is he hiding it from me? And what should I do?
