I have been kind of forced into friendship with this girl. She's nice, but extremely selfish, bossy & inconsiderate, and constantly puts her own needs above everyone elses. I was fine with just keeping her at a distance up until now when she has decided to come to the same uni as me next year. The problem is, she flirts with every guy constantly, and seems to be more attracted to guys that are off-limits, (i.e guys that me & my friends like) We have tried talking to her about it, but she refuses to listen, and just tries to get with them anyway. She is very attractive, so obviously the guys like her, and it just means that me & my friends have to compete with her to get the guys we want. Last night I saw a guy I have been really into for a long while now, and when she saw us talking she came up and started flirting with him too. It bugged me because its hard enough for me to talk to people I like without having to worry about her trying to sabotage my efforts. I don't know what to do about her, whether to confront her again or what to do...
