I have a boyfriend but I hang around girls and im bi and I dont know what to do :(

Im bi and I hang around a heap of girls an they are all very pretty but I hang around this girl alot and she is like my best friend and we talk about EVERYTHING(well she thinks anyway) and I think im kind of falling for her and I dont want to tell her because I might break our friendship.. but then again I do want to tell her because I want to let her know how I really feel, any advice guys?

Have a general conversation with her on female relationships and listen carefully to what she says. Something like, "I saw a photo on the Internet of two girls kissing, could you kiss another girl?" If she says "Yuk," forget it. If she says "Yes" or "It depends on the girl," ask, "How about me?"

Don't make the mistake of picking out someone and investing a lot of emotion until you know the feeling is mutual. That will put you in the same position your BF is in right now.
