i disagree with the comments in here...
even after she sent the long text.. if you think your friendship of 9 years is not worth letting go.. you should tell her everything you told us and just talk to her.
my ex bff and i have said hella things we didnt mean while annoyed with each other..
i have 'stopped being her friend' and vice versa many times..
it really cant be this serious... over you hanging out with her... shes just hurt..
but you also feel a way about her canceling last time you tried to have her come to the game..
but neither of you want to be the bigger person and put aside your annoyance and really talk it out..
if you value your friendship at all.. dont let it go over nothing.
