I'm having a get together on Saturday for a 'big' birthday - quite casual, a picnic at local country park with cake and fizz. Invitations went out via text and Fbook a good couple of months ago.
So, all close family and quite a few friends are able to come...quite a few can't but it's a busy time of year and that's fine.
However, my oldest school friend, who lives locally, who I'm in fairly regular contact with (meet ups a few times a year, buy for each other's Dcs birthdays) and who is kind of like one of the family, has only just replied 2 days before to say she won't be coming. I've sent 2 or 3 texts chasing since she was the only person who hadn't responded and I finally texted today to ask if everything was ok since I still hadn't heard anything. AIBU to be pissed off that she clearly doesn't value our friendship enough to a) be there and b) bother to let me know?
I'm really bad at confrontation but really do feel like I need to say something about this. Should I? If so, what?
