Around 15 years ago, in my 20s, I had a really close male friend. We lived in the same city for a couple of years, and socialised a lot together and as a group. Entirely platonic, no suggestion of anything else.
I got a job in another city but we stayed in touch and continued to socialise, albeit less often. Then, out of the blue, he stopped making contact, and deleted me from social media. I didn’t follow up with him about it, pride mainly, but I was very hurt at the time. Things moved on and had no contact at all for over a decade.
Recently, my employer engaged his employer to work together on a project. I mainly deal with someone else on it but the other day, we exchanged emails regarding the project. No mention of us ever knowing each other previously, entirely professional exchanges about the work.
He must have known it was me as my name isn’t common, and now I don’t know what to do. Should I acknowledge that we knew each other before? What happens if we have to meet face to face - not likely as he’s not part of the core team, but not
impossible.
It’s just a really awkward situation. AIBU to just carry on without mentioning anything?
