This is such rude behaviour, and upsetting for the person cancelled on. Sorry this happened to you, Carmella.
Sadly, it's happened to me quite a few times. The worst was a few years ago, when I invited 3 friends round for dinner & drinks. One cancelled 2 days before, (legitimate reason).
I then texted the other two, making sure they were still coming before I shopped and prepped everything. They confirmed yes, they were coming and looking forward to it.
The day of the dinner, one of them messaged mid-afternoon to cancel (she had too much to do for her child's party at the weekend apparently)! An hour later the other one cancelled, saying she'd had a stressful day at work and can we do it another time.
I was so upset, everything was ready too. They didn't even seem that apologetic, just all started talking on our group chat about another neighbour's party we were going to at Christmas. Maybe the evening I was putting on wasn't 'enough' for them? Who knows! I don't see them much anymore, such hurtful behaviour.
I hope you & your dh do something nice this weekend. x
