How would you react to this?

Wow hell of a story. People are usually like that it's called conniving and underhanded. I used to know people of this sort and they thought that doing that kind of thing was fun. First for the guy I think he's a fool walking around and talking about women who worked closely for years probably before he even got there. Yeah that would be a good reason to tell another friend what is going on and watch the guy who is trying to kick it to you because when you are not around, he gossips about people. About the girl or both of the women you spoke of they should have known what he was trying to do if he is gossiping around about other people to other people who know each other. I think I would handle it like a regular day and when I get her alone just let her know where her Shh stinks at, and keep it moving. Sometimes friends are not who we think they are. So let this be a hard lesson in life where you don't trust anyone, sometime not even your own husband as unfortunate as that sounds. Hey look at all the stories there are on here and watch what Im talking about.
