I know ultimately it's none of my business, I just found it a little odd he kept quiet.
A man I'm friends with at work, I found out his ex was my former line manager. I still work in her department but I'm no longer her direct report as they did a bit of rejigging of the teams.
Apparently they dated around 7 years ago in their place of employment and she ended things, he's been single since. Apparently it's 'put him off' dating at work.
I only know because he walked past our desk and she said 'Guess what, I dated him in 2017'.
I didn't even know they knew each other.
I talk to him regularly and he'll have seen me sitting and talking with her in the office.
They both worked at a restaurant chain apparently and dated then. He's told me all about her without telling me it's her
Apparently he acts like he doesn't know her. He's been here 2 years and it's highly likely he's seen her, as I say I've sat next to her several times and he'll have seen this.
As I say it isn't my business, he doesn't have to tell me, I just find it a bit odd. I've no intention of saying anything to him unless he brings it up.
