life update my feelings are confusing again

me and B. talk like all the time now. We text non stop and we talk at school really often and i'm shocked how everything turned out. 
We've been flirting like crazy. sending eatch other suggestive videos and just talking like we want to makeout immidiately. we both know we're joking but sometimes she texts me"I' serious" and i'm like "i know" cause i don't actually mind it. but sometimes i wonder if i really want her. i know it's just a crush but i don't want to hurt her again. i know it would hurt twice as much this time cause she told me herself that she actually enjoys talking to me right now and i changed really much. i never want to hurt again cause she's the sweetest person ever but i feellike my crush was stronger when we weren'ttalking yet. maybe it wasn't even a crush i was just missing her it didn't have to be a real crush. but sometimes i think about us and sometimes when she calls me a pet name it feels nice and i like being close to her physically but i'm wondering if i want it to be something more or not. she's staying over the weekend and we are joking how we're going to be freaky with each other and make out but i'm thinking do I really want that or am I tricking myself and forcing myself to have a crush on her?
