Does she like me, really hate me, or did her friends brainwash her into not liking me?

So about a year ago i met this girl through my friend and his now ex and well instantly it hit me that i liked her and well we spoke everyday and the four of us did stuff(no not that....or that) everyday just about and my friend and his ex said we should go out but i asked twice and she was busy both times. we still chilled but we didn't exactly think of it like going out. her best friend said she liked me and i said ive asked and she never really gave me an answer. i went away for the summer as a counselor and when i got back first thing i did when i got into service was text her. I never got a reply. When the school year started it was like any normal day we talked i made her laugh but she didn't seem the same around me. I had heard that her friends we bad mouthing me while i was away and well she hasn't really spoken to me since i got word of what was being said about me. Here and there we occasionally see each other in the halls and i will nicely smile but i would get this upset why are you looking at me face back. Ive tried to ask what the problem is and i never get a response and as much as i say to myself move on, i cant. i see her and well my body does that weird crap blah blah and well shes never out of my head. should i move on wondering or go for it all and just make her answer so i could be answered as much as i would love to her the answer im looking for it would be nice to have this chain be broken and maybe i could concentrate in class again.
