I've been close friends with Emma for 16 years. We used to live in the same city but she moved back to the small community she's from.
Now we rely on visiting each other or taking trips together. Last year, we went to a weekend event in a city between where we both live. The hotel next door to the event is 170 per night, so we first spent a couple of nights in a cheaper hotel nearby and then moved to that one.
Circumstances have changed since last year - I left my job to do a Masters for one year as a mature student and she got a better job with a good salary. She knows I'm on a student salary. She asked me to do the trip we did last year again, and I agreed. She mentioned she didn't want to go back to the cheaper hotel, 'I think that first hotel had cockroaches'. As someone who has decent standards for hotels, it was all 100% clean and tidy, it just hadn't been updated for a few years. Her comment was extreme.
A couple of weeks after her trip suggestion, she messages to say 'I decided to treat myself and booked all nights at the main hotel'. I replied I couldn't afford that so I would need to do similar to last year. She said 'fair enough'.
AIBU to just think she's so rude for inviting me to do this then booking this expensive hotel for herself without a discussion?
