I started a new job a few months ago. It happens to be the place where my ex of over 10 years works (my taking the job there had absolutely nothing to do with him, it was too good an offer to turn down and we work in the same industry).
Since I started, he's basically been telling everyone we used to date. For example he approached my new boss and said "I believe you've just employed my ex girlfriend", and a few weeks back I was chatting to another new colleague and he mentioned my ex. I said yeah I already know him, and he replied "I believe so, he's been telling everyone you have a history, I think it's like a badge of honour for him".
It's getting a bit tired now. Especially as I want to keep any relations strictly professional and I technically senior to him too. I just feel a bit embarrassed now by his constant sharing of our intimate past (which is ancient history!) with all my new colleagues.
I am on civil terms with him and always have been, so I don't want to create an atmosphere, but I need him to just stop repeating this story to everyone. I'm finding it awkward and I don't want people to "talk" if we are in meetings etc together as part of our job roles, as I just find that really uncomfortable and unprofessional.
I guess my question if am I overreacting or being overly sensitive here, or would this annoy others too?
