Hey........Im not gay but I thought I would be nice and try to help you.......I dont no how much this will help since I dont no the whole story and I dont no how you feel abt her cuz i've never had feelings for a girl but if your heart says to tell her then you should, but be sure not to say it in a way that would totally freak her out. She probably will freak out but hopfully not to bad! And I no some girls here who act like they are gay, but I no that they arnt really, so the answer to your question is yes there is ppl who joke around about being gay. But hey thats jus my advice....like I said I have no clu abt the whole story so ya!
