Is it normal that im in love with my girl best friend?

Idont know if this is normal, but... I think im in love with my best friend thats a girl...? I met her last year in september we became very close these past few months. I mean weve became very very close, like shes kissed me multiple times, she flirts with me, she looks at me like she wants me or something. I like her shes very chill, cool, funny, beautiful, and we have a lot in common. We spend every day texting till one of us falls asleep. We try to hang out everyday cause i moved schools but im going back to my old school. Anyways i think im falling for her idk if she feels the same but it seems like it we are very sexual towards each other when we text and she also barely told me shes bi sexual and idk ever since she kissed me and ive had this weird feeling for her i think imight be bisexual too? I need help!!!!!!
