Scorpio Stare Confusion

Well just call them person one and person two and ill try to be breif. Person one is just rude she always pushes me into lockers, messes up my hair, hits me , calls me a bitch and tells me im ugly. Me and her got into a few physical fights. It doesnt sound like much but its ALL the time! Since beginning of freshmen year! Im now a sophomore.. now person two. She has started rumors about me, told people ive tried to get with her and she acts as if she hates me. But she never takes her eyes off of me! The longest she stared was like 15seconds. And smiled at me once (during a sexual joke. Just putting that out there lol) and if me and my friend would walk by, she would just stop talking and just stare at me. One day i asked her for my test score and i was standing next to her and she kept looking up at me and stuff. People have told me she likes me because of the way she acts. But i dont know. Any help on either one? And im a girl. Just saying because i dont want people to think imma guy hitting a girl, any help would be much appreciated! thanks!
