To have uninvited her after she failed to respond to my messages?

[wisteriasmoke]

Yesterday, a friend of mine was feeling under the weather and transferred her reservation at 20:00 for this restaurant I'd been dying to try out to me.

I messaged another friend about it and we made tentative plans to meet up after work. I told her to text me a confirmation by 18:00. 18:30 comes around and still no reply (she didn't pick up my call either), so I found someone else to have dinner with.

At 19:15, the initial friend I'd invited sent me a message telling me that she was done with her workout and was ready for our dinner. I apologised and told her that I'd be going with X instead.

Friend replied with something passive aggressive. I asked if I should've waited around not knowing if she would decide to go or if she would ultimately cancel at the last minute 'like before'. I got a 'LOL so petty' as a reply.

WIBU?

Her loss, especially with the invite being for a place that's hard to get a table on really short notice. Put her on the "B List" for next time. Who knows? She may even find someone else to put up with her flakiness, and let you off the hook.

Sounds like her workout was too important to miss, and she gave you a noncommittal "We'll see". You weren't the least bit unreasonable to prioritize the reservation over your friend's workout.

She sounds horrible. I'd bin her off.
