Worked at a place for 1.5 years, got on with my colleagues really well I thought. Some left around the same time I did and some are still there, but we were all on a big group chat together.
Some people left the group chat quite early on but I tried to keep in touch with everyone and organize things.
There were 1/2 things I couldn't go to which were organised, but I went to one thing last summer which was great.
However the group chat seemed to die, nobody ever wrote on it and next to nobody replied, so I deleted it in the end as it seemed a waste of time, however I still have their contact details and they have mine.
I have briefly spoken to one or two of them on social media in recent weeks.
Last night some photos appeared on my social media page of a group of 10 of them out for a meal. I admit I felt a bit hurt I wasn't invited. The ones I had recently spoken to didn't mention a thing, and surely it's not because I deleted a group chat that was no longer in use at all.
Just makes me feel a bit hurt that they never really liked me that much, or maybe they started their own new chat without me. This is a group of people between 30 and 60 years old, not some high school event.
Should I bother contacting any of them again or just move on?
