Uhm lesbian tea gays, do i like her??

This is not reddit but i know yall are gayer than any gays out there so i need your help. Okay, so I have this classmate, she's lesbian and a masc and I, also a lesbian and her friend. I yap to her nonstop cuz we're friends but not close besties something like that. Every time I was in our classroom, I kept looking for her and idk whyyyy. Sometimes I feel mad about her chatting with her online girl friends during class but I don't know why I'm mad. She lets me lay my head on her shoulders, she lets me sit in her lap, and even let me use her phone but ignores me and only talks to me when his phone is low battery one time i told her that i would confess to her as a joke but she told me that she would think about it AND I DIDNT DO ANYTHING CUZ I DONT KNOW IF I LIKE HER. what do I do?!?!? ╥﹏╥
