Twat at work saying he's slept with me - want to explode

[Bottlevolley1]

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?

Don't start telling everyone about his tiny penis, don't say anything that gives his lies reasoning. Speak to human resources and tell them everything.

Wow. What a piece of work.

Agree with pps, straight to HR. Telling people he has a tiny dick won't solve anything ( at that even being suggested as advice).

Speak to HR for sure.
For all you know it could be the bloke who told you shit stirring and x colleague said nothing of the sort. Who knows?
Tell HR who told you what and regarding whom. Don't engage in any conversation about the matter with colleagues, tell them HR are dealing with it and you'd rather not discuss it thanks.
Good luck, it must be horrible for you.

A similar thing happened to me once when I was about 24. I met a guy who worked in a different firm but in the same industry and we had mutual friends. I went on two or three nights out with him, either in a small group or with the mutual friends who were a couple. I snogged him once when I was drunk but politely rejected the offer to take it further. He got a bit of a thing for me and asked me out a few more times but I just didn't fancy him. I was never horrible about it though, I didn't humiliate him or anything, but he got a bit shirty about being rejected.

About a year later it was Christmas and I was opening a bunch of Christmas cards sent to my office from clients/suppliers etc, (those printed corporate Christmas cards) and one was from the firm he worked for. It was sent anonymously but addressed to me and there was some vile hand written message in there that basically said I was an ugly fat slag who had ideas above her station and I should be grateful for any male attention I got.

I did nothing about it, I was young and I just felt mortified by it. If that had happened to me now I'd be straight onto his HR department and possibly the police as well. I really regret that I didn't do that at the time.

It's the Other male colleague has begged me not to trace it back to him that makes me ...

you describe him as a better friend, yet a good friend would be more then happy to go to HR with you & repeat what they heard/told you.

Why is he concerned about that??

You don't know if the rumour is actually out there or if the guy who told you has an agenda.

Either way, you absolutely need to go to HR with it.

Keep your cool, tell them you've been told that this rumour is circulating by man 2, you don't know if it actually is, but if it is, it needs dealt with and that it's extremely unprofessional and untrue.

Let HR deal with it, but the must deal with it and they must document how it's dealt with.

It's an awful situation and one that leaves the company open to all manner of HR issues if they fail to act.
