Does this girl like me? im also a girl?

For the past 2 months of school ive noticed ive had this new attraction to this girl in my school. She is in my class and was also in my class last year. ive noticed that in class she looks at me and smiles a lot at me. Her personality is usually naturally bubbly but i know she has a history of cutting. she tends to tell me a lot about herself, and what shes done. I have also flirted with her over facebook messaging and in class. she always calls me amazing and stuff of that nature. she insists on sitting next to me on the train and when we go to six flags. she would like to brush her arm against me and when on the train i fell asleep on her shoulder i felt her breathing into my mouth. i know for sure shes bi because she told me the girl she likes. she leans into me a lot and sometimes even says she loves me. she says AWWWW a lot whenever something comes up. then, just yesterday in class she started to touch my hand and arm with her feet/toes. at first i thought it was an accident but it kept going on.when i turn to look at her and smile shes looking back at me. then she holds my gaze and smiles. then after like 10 minutes of that i swing my arm so im tapping her knee/ leg with my hand. after a few no contact swings she moved forward like 6 inches and sat on the edge of her chair so whenever i swung my arm we mad on-point contact. then at the last 30 minutes of class she would push her leg up against my hand. before this at the beginning of class she rand her hand up and down my leg. then she crosses her legs and i started to swing my arms again and after a minute or two of that she went to the bathroom. then later as i was sitting under a desk directly across from her with my legs out she put her flip flop(with her foot inside) on my leg. then i was like, "your shoes" and then took her shoe off and rested her actual foot on my leg . i was like "your foot is cold" then she was like,"your really warm" then she moved her foot up and down my leg. then on FB me being me i say "why don't you talk to me anymore?" and then shes like "??????" then she put " I ******* LIVE YOU" THEN, "WHOOPS LOVE" then i asked what that meant and then i said, well i love you too. WHATS GOING ON??? please help
