Don't wait too long before you confront your friend about her rudeness. Take a bit of time to cool off, and then talk to her. The longer you let it go on, the longer hurt feelings can fester. In addition, if you let it go on for too long, your friendship might drift apart. Ask her to meet you in a neutral location where you'll have a bit of privacy, such as a coffee shop or park bench.

Tell your friend what she did to upset you and why you feel it was rude. For example, let her know that her rude language or the fact that she walked away from your conversation to answer her cellphone made you feel unimportant, left out or angry.

Keep your emotions in check. When someone is rude to you, it can be hard to keep your hurt feelings or anger from cropping up. But getting emotional can put your friend on the defensive and make her feel attacked, which won't make it easy to resolve the problem. Stay calm and use a pleasant tone of voice to let your friend know that her rudeness upset you, and then talk about how to prevent it from happening in the future.

Talk to your friend without other friends around. The sooner you address the rudeness, the sooner you can resolve it. However, it's important to talk things out when you're alone because a group of your other friends might start taking sides. This can elevate the conflict and make it difficult to work things out together.

See your friend's perspective. Maybe she was rude to you because she got bad news, was laid off from work or was jealous about your upcoming wedding, promotion at work or new pregnancy. If this is the case, her rudeness probably didn't have anything to do with you and was a reaction to something else. Try to be understanding about this and it will be easier to resolve the conflict and move on with your friendship.
