I plan on cutting up a friend because of a single concise conversation.
Why sort of conversation was it?
She was being completely non-understanding and rude to me.
I know you're hurt, but you should still treat your friend well. They'd be upset if you broke up the friendship over something so petty.
I shouldn't give a shit about anyone who acted that way towards me.
I get what you're saying, but I think it would be beneficial to have a chat with them about this. Simply talking with them could repair any problems going on with your friendship.
