I recently had a huge falling-out with a very close friend I met in high school and kept in close contact with after I graduated and went to college. She dated, to me, a very degrading and mentally abusive guy whom she insisted she loved anyway, even though he called her fat, broke up with her often as a joke, went out of his way to make sure she knew he was intentionally ignoring her... you get the picture. They eventually broke up, and she became pretty depressed. Well, semi-recently, she had a huge change of heart... or something. Her attitude in social situations changed almost entirely, her flirtations and encounters with boys developed exponentially. I was really happy for her--and don't get me wrong, I still am--to be over Asshole Boyfriend. However, she took it a little *too* far, to the point where she was insisting on being the center of attention in everything, bragging to her close friends about these other great friends she had made, even insulting us because she thought it was funny. Now, okay, I didn't want to just sit back and watch a friend spiral down the wrong direction, so I tried to bring it up to her about associating with the wrong kind of people. This backfired horribly, and ended with her telling me I had ZERO right to "tell her how to live her life," and that I was "one to complain," then listing off ex-boyfriends she knew I viewed as mistakes. I dropped the issue. A mutual friend of ours finally called me and said that most of the people she was friends with (they had just recently met this ex-friend) had been complaining to her about her immature "drama queen" attitude, but she wouldn't tell me who, she just made it clear that my next best course of action was to talk to her and try to get her to calm down. I thought about the best way to do this, after our first encounter. Ironically, the next day one of her new "friends" approached me, laughing about how "she was complaining you're too hot for her" and that I should "know that a fat, hairy dyke wants to clam joust with you." This basically pushed me over the edge, and I resolved that if these were the kind of "new great friends" she was hanging out with, I didn't want to be a part of it. I brought it up to her (the comment made by the above asshole) and she shrugged it off as though it were nothing, then asked why myself and our mutual friend had been seeming distant. I told her it was because of her attitude, how she had developed to be a "center of attention" drama queen, and quoted what our friend had said. Needless to say it didn't go over too well, and she believed what she wanted: Our friend didn't think those things at all, and I was personally just being "mean, vindictive and judgmental." She left our group of friends, telling none of us to talk to her anymore. Our now-not-so-mutual friend (for she told me she was glad to be "rid of her") text messages me now whenever this girl approaches her, laughing about everything she says, and makes it clear she's pretending to be friends with her for her own amusement and for the amusement of her friends--which she tells as well and laughs. So I'm stuck in two ways here, one being that: I don't think it's fair that I'm the only one who gets to look like I thought her attitude was immature and inappropriate, and the second: While she's changed drastically, she's still (somewhere) the person I was best friends with for over seven years and I feel like it's wrong she's getting played like this. I don't really want to approach her because I definitely don't see it ending well. Our ex-mutual-friend refuses to talk to her and tell her to her face what she thinks, an explanation for this from someone else being "Well.... that's (name) for you." So, I'm asking you, People on Yahoo Answers, what you think, and what you'd do.
