It was a friends birthday recently - a significant birthday- so a small group of us went on a trip away to Barcelona.
As well as spending 100's of pounds on the trip itself I bought her a present which cost about £40.
While on the trip she splurged on herself - treated herself to lots of stuff (designer stuff). I would estimate she must have spent about £2000 on herself in the space of a few days.
My birthday is a few days after hers - not a significant birthday, so I wasn't necessarily expecting a present - but despite all the effort I made for her she didn't even buy me a card. Same thing happened last year. There are some other issues with her also although she has been a good/fun friend over the years.
AIBU to be sitting here thinking that the fact that she didn't manage to even spend £2 on a card for me in the context of a weekend away where she spent literally thousands on herself is a bit revolting. Am literally feeling a bit disgusted by all the conspicuous consumption. 
Have just started to wonder whether this is the sort of person I want to hang out with.
