This business of not calling a wife by her first name comes from a segulah. There is a segulah(no, I don’t know the source if anyone can help me out here please) for aruchas yomim if you don’t say her name.
That brings many to say “hernor”(hear please) to get their wife’s attention.
But this is really not common practice.
I for one, want my husband to live until 120, but I wouldn’t exactly appreciate being called hernor…
