Is this girl bipolar?

Arogers
Alright so I've liked this girl for a couple months in my class. In the beginning we would lock eyes a lot and both blush and it would happen quite often however she has a lot of mood swings. I told her I liked her and got rejected. She joked about liking me over text before rejecting me. We stopped talking much in school however she began dropping rude comments or just conmenting over almost everything I say even when I'm not speaking to her for example I would ask a classmate something and she would answer or I would come to school early for once and she would be like hmph you're actually early for once. She even told her friend she kinda liked me and then fully denied it when I confronted her on it. After this I didn't see her for 2weeks and didn't text her either. When I do start seeing her again after the first week she texts me that she wants to hook up and lose her virginity and that she's serious. I didn't believe her but I asked her why me and she said that out of all the guys I seem like the best choice and she doesn't have time for a relationship right now. I tell her ok under the condition that she's sure about it. She asks me why I agreed and tell her I dont have to tell her that. She continues speaking to me about music etc until 2am that night. The next morning as i'm getting dressed she asks me again why I agreed and tells me that she's dressing etc. I get to class and we still dont talk much. She's much more reserved around me than other guys after finding out that I like her. After school I hug her from behind to see if she's comfortable. She isn't and tells me that by hugging her out of nowhere I took away her option of hugging me back. The next day I walk her home because her bff was busy and we talk and laugh and for the first time she hugged me really tight and smiled the entire time. I told her over text that I wanna go out with her and she said that she thought I moved on and she doesn't like me that way and now she has once again distanced
