What Should I Do about how I Feel?

I met this girl about a year ago & now were best friends ,but I'm feeling a stronger connection & I don't wanna be just friends ,cause I'm in love with her. It's just obvious I think she's beautiful & I always put her first even before family. She makes me feel special & when we hangout it's like an escape from everything. I could look into her eyes forever. Anything she wants me to do , I'd do it without thinking. If she was dying I'd be by her side no matter what. See the thing is she has no clue how I feel & I have no clue how she feels. She just has been sending me a vibe that shes bi. I mean she wanted to take a shower together,she asked me to suck her toe, she asked me to touch her stomach & her leg. One time when we were walking around my town, she asked me if I'd want to know if someone I knew was a lez. She told me she was wearing nothing under her shorts when she was laying on my bed next to me. She asked me to carry her in my arms. She wanted me to mage her feet. She used to always wanna see my stomach. She wanted to get me high & drunk. She told me she likes to take advantage of people. She told me she used to make out with her friends. She wanted me to come in the bathroom while she took a bath, but luckily she was wearing a bathing suit so it wasn't awkward. She wanted me to come in the bathroom with her when she changed her tampon. She does this thing where she sucks or kisses her knees & then she sorta looks at me. She walked into her bedroom one time while I was laying on her bed & she said" I'm back" in a seductive tone then flipped the lights off & then turned it back on & said" Omg why did i do that?" Idk if anything I'm telling yu will help ,but please help me make sense of what I should do. :( I'm falling for her
