text: You are not doing anything wrong. It sounds to me as if your BF is a little jealous and upset because you are doing something with someone other then her. Don't let her get to you, just let her know that if she can not control herself and act like a BF and be supportive then you don't need her to be at your party. Not trying to be mean but the purpose of a party is to have fun and you can't do that if you are constantly defending yourself and your other friends to her.
