Do you think she likes me more than a bestfriend?

Alright so me and this girl have been bestfriends for about 2 years now...we are both 15 and both girls. Ive always umed she was straight because she seems interested in guys and is super religeous and kind of a ! Anyways, shes been acting different for some months now. We flirt all the time and everything but now whenever we hug its like a really long hug like more than just a friendly one. When we watch moies together she snuggles me and like pushes her up on me and presses up on my n stuff. Shes been all over me lately like always touching me and rubbing against me. I started rubbing her legs when she was doing it just to see her reaction and she didnt question what i was doing she didnt mind it at all! then she sits on me and i can feel her breathing on my face. she always stares at me wen were with other friends and always touching and grabbing me in some way. ive had feelings for her for a long time and i really wanna know if she likes me back!! this has been driving me crazyy soo please help!!! she also calls me cute names like sweetie, baby, ect,....she always ssays she wishes she was with me and always wants to spend the nite and when she does shes all up on me. When were snuggle or whatever i can feel her heart beat and she swallows hard but im not sure if shes into me as more than a friend or just a really close friend????
