Short version...
Group of 8 friends
2 fall out quite badly (a & b) but it involved nobody else
A is making new friends but making it clear she dislikes b - being rude, ignoring on school run etc
B is annoyed with us all as a few of us still try with A and she cannot understand why we are making an effort when A is being mean to her
I hate all this. I am an adult and can make my own choices. I don't have blind loyalty and don't want to cut A out. B is very upset and thinks if we were real friends we would back her up.
I have never had a large group of friends before but it all just seems like a minefield!
B thinks if would be weird if a few of us had a play date with A but surely we are all adults and not sheep
