AIBU or am I being petty?
We are having a late end of summer party. Around 30 people in our house/garden.
I mentioned it to a friend/acquaintance and they immediately said that lots of people might not be able to come because it's the same date a big concert. I told them that yes, the concert is on the Saturday and the party is on the Friday. They said they wouldn't be going out the day before the concert.
When sending out the invites, I thought to save any drama, I would ask them if they would like to come. They repeated that they had a concert the next day so wouldn't want to ruin that - and asked how late I would expect it to get. Oh and they would actually need to double check their calendar because they think they may have something on anyway. So I just left it at that.
Then I got a message a few weeks later asking for a follow up and details of the party. I asked her if she was now free and wanting to come? She said she would try and come but she has other plans until 8:30pm and the concert the next day.
So I added her to the whatsapp group with the details.
Next morning (day before party) she messaged to say that unfortunately she now has a sore throat so won't make it because she doesn't want to risk it being more ill for the party. I just ignored and removed from the whatsapp.
I've now had two people message me to ask why that person was removed. I just said she said she couldn't make it.
Now on the day of the party (today), the friend has messaged to ask if she is actually invited or not to the party! wtf?
DH thinks I should just ignore her, but as we are in the same social group it is awkward.
