re: If someone uses the term “significant other” or “partner” do you assume they are gay?

Had a guy join our department last year and he kept referring to his partner when we interviewed him and since in all discussions.

I assumed he was gay based on that, but I don’t act any differently around gay people so no biggie. Blew my mind when he mentioned her name months later and I was like “what?” She is also his fiancée, so I am not sure why he would not just call her that.
