Please someone help with my question?

I agree with you. You should be mad at her if you are telling the truth about who she invited who isnt really her best friends. I believe best friends are the people you must always choose first in parties, or trips or anything like that. I guess no need to do comebacks, do not do the horrible things she has done and just ignore her... (works best with a group of best friends who are close to her too.) Do that for a week and see if she will come dying to come back. If she doesnt within a week or so, then i guess either she doesnt want to admit she's wrong or doesnt want you as a friend or something.

Anyway the choice is yours, I am just saying I support you here. Good Luck.
