Two of my friends at school - guy and girl - they're really good friends, and recently I and some other girlfriends have had suspicions that the guy, Tim, really likes the girl, Abi. I'm sure I'm right, there's little hints, like the way he talks to her, and he always plays with her hair, stuff like that. I told Abi what I think, and she disagrees, and says even if he does like her, she's just good friends with him and wouldn't go out with. So that's fine, right? But when she sees him, she acts overly flirty, even more so than normal. It's as if she's leading him on?! But why - she doesn't like him like that, and she knows he does. I don't know why, she is the type of girl who would do something like that to seem popular I think.... but is that not a bit mean?!
Edit - I should add, she's done stuff like this before, she acted so flirty with a guy she knew liked her, when she didn't like him back, and when he asked her out she said no, saying they were just friends and he had totally the wrong idea.
