Because she's weird like that.
She's hard to explain. She likes to completely knock people's defence down and break them, then put them back together again. She also likes to play mind games. Don't get me wrong, she is the most amazing friend you could ever have. She's just, well I think she has mental issues, so do a lot of people, but she swears she doesn't and she won't go and get tested or anything cause "she's fine".
Hope he says yeah for ya.
