How to approach W about OM

[OfficerInNeed]

When the phone calls first started to happen my wife did tell me she called "someone" for advice and then later told me this someone was a co-worker. The more I opposed the communication the more she became defensive and secretive about the calls.

I then started to hear from people OM did not know I knew that he had said "I don't know how this happened but I think I became "W name" best friend" and the also said "I can't wrap my head around it, she follows me around like a puppy dog."
