What is her problem? What should I do?

[Jay]

Hey everyone, so this girl likes me (110% sure) but I dont think I do anymore, now she tries to turn some of my friends against me. She would do everything to get my attention but I ignored her. My friend told me she called a pussy and she claimed to move on but in class I caught her staring at me very subtly and FB she kept posting statuses (around 8 last night) about the perfect girl ur missing and similar stuff. lol, I mean should I give her a chance? If she likes me that much is she mentally sick? Im starting to feel very bad for her. I didnt see her today because I am about to drop out but Idk yet.


I also noticed her hair is different and puts extra makeup and I add a job (FB page) minutes later she did...
