I don't have any social media accounts because I got sick of it all years ago, but reluctantly have a LinkedIn profile for work reasons.
A uni friend who hasn't spoken to me for 10+ years messaged me on LinkedIn (so the only public way to contact me, in context) saying he was wondering what I'm up to now, essentially because he has regular catchups with one of our other uni friends (a bit of a gossip who I'm also no longer in touch with) and wants to report back to them on what I'm doing now. I don't like confrontation but this feels quite rude? Aibu to say so?
To note, this friend effectively 'dumped' me via Facebook shortly after we graduated saying his gf (now wife) wasn't keen on our friendship and he had to honour that, so we wouldn't be able to hang out any more. I'm aware his wife is quite controlling but our friendship had always been platonic on both sides, and I'm definitely not a flirt or seductress type. I'm quite plain, shy and geeky, and had a long-term boyfriend at the time.
