I tried to start this thread a few weeks ago but accidentally put it in the Coronaviris section.
Basically it's about a friendship with a colleague. We met at my previous work place over 20 years ago when friend was on a placement there. She left, I moved jobs and she was already there. We picked up our friendship and were quite close. We got on really well and dh and I went to her wedding, we would go to hers in our lunch break, we had tea after work occasionally and later on, took our ds's on days out. I was then off seriously ill for a couple of years and she was supportive, visiting me at home etc. When I returned to work I immediately sensed a shift. While I was off she had become very close to a group of much younger colleagues. I felt awkward around her because although not unfriendly it just felt like she wasn't interested in our friendship like before. It sounds petty but she moved away from sitting together to the other people. There was an issue around a celebration she planned for one of her new friends. I wasn't invited along with various other people whereas other people that she wasn't specifically friends with were invited. Jump to lockdown and i thought I'll get in touch and try and rekindle it a bit. I texted her how are you etc and she replied ,,"I'll call you tomorrow, it's easier to talk". I say "OK, that's good". Following day, no call. About a week later she texted me to say "Sorry, I forgot to call you last week. I definitely will tomorrow, i won't forget". I replied "No worries etc". That was about a month ago. I've heard nothing. I've considered contacting her again as if nothing has happened or asking her what's happened to our friendship or just leaving it now. We never had a falling out or grew apart gradually, it was like she just suddenly changed.
