Hello. I may be being unreasonable but I've seen on fb tonight that a group of ex workmates have gone on a night away. I haven't worked with them for over a year but we're still in regular contact ie we always still do Xmas nights out and in the last year they have attended some major life events of mine and I have for them aswell. We're still close (or so I thought) and I appreciate they all still work together but I'm a bit hurt.
