Friend problems- who and who not to invite to my party?

Don't let Danielle control you! If Felicia is fine with her, that's ok! If you guys really are good friends, then Felicia won't mind. Even if Danielle tries to ruin your social reputation, you can't be trapped in her web. Make yourself likable to most people-later reject Danielle, and when she tries to get back, most people will be a little uneasy but you will have an advantage: The attacker most likely will sound unfair, so that's an automatic plus. Then, since you aren't making a big deal, people will gang back up on her. Try that! I hope you have luck!
