A friend who is a colleague (male) today approached me and asked me how I felt about x colleague (another supposed friend who is a colleague.) I said I liked him, we got on etc. He said, "well I want to tell you that he is bragging to the blokes here that he has had sex with you, you got obsessed with him and wouldn't leave him alone and he had to get the police to give you a warning. I didn't think that was true of you so I wanted to check?"
Backstory is that when x colleague and I first met we were set up on a date by two friends. We both agreed at the end of the date we were not interested. He said it first, if that means anything - fine, and I agreed! That was that. And we've been friends ever since, both got married and had DC.
I can't believe he is saying this FIVE years down the line. I am married now FFS and forgot about him the moment the date ended for years ago, and am absolutely incensed that he would make up this story about me and expect it not to get back to me.
Other male colleague has begged me not to trace it back to him, so I am a bit stumped as far as confronting x colleague goes.
What am I supposed to do?
