My friends and I have a long standing arrangement where we go on a night out every three or so months, this has been going on for about four years or so. Three of the girls I've known since primary school, the other four have joined our friendship group over the years. Between kids, work etc we only tend to meet up on these nights out, although the three longer-standing friends are ones I meet up with on a more regular basis.
I usually struggle to attend these due to childcare issues and can only meet up for the nights out maybe twice a year max. I don't want to get into the ins and outs of childcare but DH and I work around each other to accommodate this which is ideal in some ways but not so great socially! Anyway, we had talked about a night out for mid March which I am actually able to go to as DH is on annual leave that week and it looked like most people were free for a night out then too. We had decided on a tribute night at a hotel with possible overnight stay (not yet booked).
Two weeks ago one of the group asked on the WhatsApp if people would be interested in a full weekend away in the summer and all of them, except one, seemed very keen on this and it was the main chat of the group for a while. I can't go as my DH only gets one day off at the weekend and sometimes works both of them, which I told them about and asked again if we were still doing the night out mid March. Only one person replied to say yes. I asked again yesterday if we were still doing the March night out and nobody has replied, although all of them have read it. AIBU to feel a bit annoyed? I don't get to attend many of these things because of my personal circumstances and I'm not sure if they're just too excited about the weekend away and forgetting about the upcoming potential plans.
