No, happily married for many years. My DH would never start a post like this if I'd accidentally lost my engagement ring, as we'd have done the obvious thing and looked for it where I said I'd lost it. (I did post to look in the trap.)
In fact, I lost my wedding (not engagement) ring for over a year, before I found it in a side pocket of a travel bag. It must have been pulled off my finger as I removed my hand from the tight pocket, as I always wore it and hadn't put it there intentionally.
My DH certainly didn't blame me for losing it, even though I'd previously had it resized and knew it had been a bit loose due to weight fluctuations after having babies.
My loving, trusting husband in fact bought me an eternity ring before I happily found my wedding ring. All of the rings are currently too large though, so they are safely put away until I have them resized.
It was devastating to lose the ring, so if I'd known my DH was online, blaming me, implying that he didn't believe my explanation of how the ring was lost and asking what others would do, I'd feel very hurt and look into why he didn't trust me.
Unlike a number of PP, you didn't see any of that in the OP, just a single word that had been misconstrued.
