About a year ago i met this girl in one of my classes and i don't know why but the moment i talked to her i knew i liked her. I don't have class with her this year but i think about her all day and we talk whenever we see each other. Everytime I see her though i feel like telling her i like her but i don't know if i should. The thing is i don't know if she's bi or lez and i'm not out to anyone. What should i do?
