YY- I didn’t realize that we were talking about a situation in which the husband is actually speaking to his wife. I thought that we were talking about a situation in which the husband is speaking to someone else ABOUT his wife.
I used to have a friend whose husband would always refer to his wife as “my wife” when he was speaking to me. Personally, I didn’t like it. I felt that it made sense if he was speaking to another guy that he might feel like it’s inappropriate to use his wife’s name. But if he is speaking to a female, I davka felt like it was inappropriate to say “my wife”.
