The Edge: Do “Work Husband” or “Work Wife” relationships cross the line?

CHARLOTTE, N.C. – A man is getting called out for his response to a “work husband appreciation” post. It started as harmless banter. The guy’s co-worker would say things like, “My husband at home and my husband at work, I’m so lucky!” Then she tagged him in a work husband appreciation post, and his wife saw it. He told the co-worker he appreciates the friendship, but to stop the work spouse stuff. She replied that “everyone jokes like that.” Another co-worker says he humiliated her. Who is in the wrong?
