Looking for views please on if this is suspicious or if I've suddenly turned paranoid. I've never been a particularly suspicious person before. Been married ages. A couple of years ago, DH started mentioning he kept bumping into his old schoolmate and his mate's wife out and about. I'd never seen them when with DH I didn't know what they looked like so could have passed them in the street and not known them. Apparently these people had lived near to us for years yet DH had never mentioned them before.
Whenever he had first mentioned them he would refer to them as 'Tony (name changed) and his wife'. This later changed to 'Tony and Tania' (name changed).
The whole thing felt a bit odd to me, but couldn't really say why.
I asked a couple of things about them, one of which was where they lived. DH said 'over there somewhere' indicating the rough area but he said he didn't know which house exactly.
I did eventually get to see them as bumped into them when with DH. Although DH seemed a little over-excited/nervous energy on approaching, I spoke to the woman a little and she seemed perfectly nice and normal. DH's mate also seemed normal although didn't really say anything to me.
The next time we bumped into them I though Tania seemed a bit different - less confident maybe - but what struck me was that she giggled like a schoolgirl at something DH said during our conversation. What he had said was mildly amusing at best, and her giggling seemed over-egged and almost nervous. Tony just seemed normal.
Recently, during a conversation about something unrelated, DH made reference to 'Tania's house'.
This sudden identification of their exact house, and the fact that he no longer refers to his mate and his wife, but just to her. It felt odd. Am I being Covid-paranoid?!
