I'm upset at my friend for bailing on my party
Why did his actions make you upset?
I don't like it when people ignore my invitations like this.
You have no idea why they might have missed your party. You should not be so upset but talk to them about it and why you are hurt.
I don't care: they still ignored it and are the reason this party sucks.
It might not be there fault though, so you should just have a conversation with him afterwards.
