Group of close uni friends, 5 altogether, all girls. Have been friends for over 6 years now.
Became particularly close to one of them over past two/three years. We talked to each other a lot and considered each other best friends.
Over time it came to light that she could be very moody and lash out at those who apparently she was closest to ie me and other 3 friends. We are her longest standing friends; others she has made along the years she has dropped (for example her first lot of female post uni housemates; she slept with one of their FWBs and things got messy). She would have "tantrums" during group meet-ups and abruptly change plans eg me and a friend flew out to meet her to go travelling somewhere and she made us change our flights home (paying a loooot extra) because it didnt suit her.
Anyway recently I have spent a lot of 1 on 1 time with her. Hosted a party a few months ago which she came to, left early because she knew no-one (i sat by her side most of the night and introduced her to people) and then was catty about the next day.
Whatever. I met up with her a few times since but the last time, she basically picked a fight; when I called her up on it and said that she wasn't treating me like a friend, she came out with the immortal line "I'm the only one you've got left. Youd best be careful". This was after I'd confided in her about a difficult situation I was having with a friend which had since been resolved. FWIW I have a fair few; she is the one who is losing them like hot cakes. I would never ever say this to her face though even in anger!!
She apologised to me three days later by text and has been off with me since. She hasn't spoken to our whole group.
I am so angry to have been treated this way! She is so entitled and spoilt
