My social life is such that I meet a few new people most weeks. I find that men, often I. The first few sentences will mention their wife or their partner, often completely out of context. They'll find a way to say I went with mt wife, or my GF said....
It doesn't matter as such. I'm not chasing them in any way, just trying to make polite conversation in the same way I do with the women I meet, I just find it interesting.
Are they assuming that I must fancy them? Are they protecting themselves from themselves or from me? Is it really just a natural thing? Or am I doing something that makes them feel the need to get it out there? Does it happen to everyone?
If takes a difference, I'm middle aged and very ordinary looking, quite the introvert, but making an effort.
