Is it normal to not know if your bi?
so i have a bestfriend. and shes bi. iv been feeling these weird feeling towards her lately. she never came on to me. i tease her all the time that shes bi, and she doesnt care. but i feel like i want to do more then just kiss her on the cheek. iv kissed girls before; nothing sexual though. and i never acctually started to have feelings for the other girls. but i almost get jealous of her boyfriend sometimes. am i bi? or weird.? i feel like i should tell her how i feel. i know she would probably understand. but idk....:/ i need help.
