How Do I Drift Apart From My “friend”?

Question by Unikko: How do I drift apart from my “friend”?
I’m so sick of her. I feel really used whenever we hang out, she always wants to come over to my house and complain about how awful her life is, and how her parents are always telling her to do her homework, and get ready for her Bat Mitzvah. (Note: she lives in a two-parent household. Her mother is a University professor, her father is a lawyer. I’ve seen the way they ask her to do these things, and all they do is ask nicely. I live with my mom (who I’m incredibly lucky for, she works so hard for me, and we do okay). She left my dad when I was six because he’s an alcoholic and a smoker. I don’t see my dad often; once or twice every two months. I’m not a bad student; I have straight A’s, I’m two years ahead of my grade in math, and I’ve won quite a few academic awards, so I think we can establish I’m not jealous of her.) She’s rude to everyone, and has said outright she feels she’s better than everyone else. If I told her how I felt she would deny that she said any of this, then go and complain to some other person…for once! She is part of her own little clique (preppy), so whenever they do something that pisses her off, she comes to me. I’ve told her I’m sick of her complaining, but that hasn’t seemed to help. I have, in the past, when we were better friends, invited her over so she could tell me about her day, and I could try and make her feel better. I thought it was my job as a friend to help your friend feel better, but really, she has no excuse to feel worn out and unmotivated, since she randomly takes days off to watch Desperate Housewives. These are billed, “Mental Health Days”. I can tell you now, this won’t fly in high school. I have plenty of other, respectful friends that I can have a two-sided conversation with, as opposed to them complaining my ear off. One fewer won’t hurt me. How can I stop being friends with her without hurting her feelings too badly? (Some hurt is inevitable, I’m sure.) She’s bringing so much negativity and frustration into my life that I just don’t want!
Let’s clarify. We used to be really good friends. I only mentioned my grades to tell you I’m not some whiny, underachieving person. I don’t want to hurt her feelings (that’s rude, and not going to help me). Oh, and if you can’t help me, don’t answer my question. I want help, not hate.

what you can do is that you can stop calling her/contacting her. when you go on things like msn appear offline and talk to the people you want to talk to. you can start to ignore her and shell maybe get the message.

if you wanted to amend the reataionship you could tell her to grow up and how her complaining is showing that she is really self centered and no one wants to deal with it. if she wants to complain tell her to go to a psychiatrist.

you can also start hanging around other friends as well and she will maybe get the message there too
