Lice!!!!!!!!!!!!!!!?

Well every girl in my class has lice, and theres not alot of girls in my class, about eight not including myself. I hang out with only one and her lice is like so bad its visible. I went to the nurse friday and told her to check my head, she didn’t see anything but im scared i might get it. Any way i went to my friend and started to hint around that she had lice. she told me her mom checks her head every day, which is a lie. but like all this year shes been like leaning her head on me pretending to fall asleep and i think she might be gay.but, what should i do? should i not hang out with her anymore? Should i tell her she has lice? PLEASE HELP!!!
Also shes the biggest rat in school and if i said any thing she said she’d tell. and whenever i stop being her friend she pouts like a baby shes so annoying but she’s the only friend i have at this school.
