I was friends with a colleague (male) for 3 years while working together. We became good friends during lockdown, he'd come out with me and my friends and we also had a mutual group.
We grew apart a bit when we started dating others but were still friendly and socialised. Our workplace became really toxic & we all became miserable - I left months ago and he was the last to leave recently.
Recently on LinkedIn, I saw that he'd liked a post about toxic workplaces. I messaged him a light hearted comment about it, in an I totally know what you mean kind of way and asked how he was doing now and how the new job was. That was over a week and a half ago and although he read it he totally blanked me.
A few days later a mutual friend invited me to a gathering he was going to & I was busy but honestly I think I'd have been embarrassed knowing he's ignoring me. Secondly, I rarely post on Instagram but I have noticed for the past week he is viewing everything I post but still not replying
I feel mortified that I said something wrong and keep chewing it over. It's weird because usually I don't overthink these things or care what people think but I've got myself into a funk about it!
