<human>: Condense the text into a few key points

We're both juniors in college (I'm 20, she's 21), and she's been in my group of friends for about a year now, but she is constantly impacting us in a very negative way. She'll blow up and complain about the littlest things. When she knows you have a crush on someone, she hangs all over them and tells them how much she loves them (she even slept with my ex-boyfriend. Whoops.). She's the kind of person who constantly puts herself in bad situations (like going to parties alone at night in suggestive clothing) and if something happens as a result of her putting herself in these situations, she complains about how awful it was (let me just point out though that nothing terrible has ever happened). She also has this guy friend. I feel so bad for this guy, because he really really thinks that he has a chance to date her, but she's led him on all semester and has no intention of being with him. She knows she's doing it too. I asked her why she does it, and she literally told me she likes male attention.

We keep trying to tell her that these things are bothering us, but she thinks we're kidding every time we talk to her. We're all so tired of her drama. We're all home for break, and we've all been trying to only talk to her when she talks to us and keep it brief, but I just know that when she finally realizes that we don't want to be friends anymore, she'll kick up a shit storm of drama. We're tired of drama. We've all had way too much of it. Is there a way to end this gracefully? Any help would be appreciated.
<bot>: this girl has been negatively affecting my life with her constant need for attention and drama, and I would really like some advice on how to gracefully end the friendship.
