My coworker Brian won’t apologize to his wife for taking his friend Justin Lee’s side over her due to the fact that Justin is getting Brian involved in his business when it’s got nothing to do with Brian, and is putting a huge wedge between him and his wife’s relationship. What is a firm way to tell Brian that he’s in the wrong and that he needs to apologize to his wife for being so mean to her? He’s been doing this for months now, according to his wife whom I talk to regularly.
