I'm in love with my best friend(a girl),but she keeps saying me "bro"?

Don't hide your feelings. I had a guy friend who liked me and told me even though I said thought of him as a brother. Months ped, and admitted that I had actually liked him all along. I just would cover it up with "bro" and stuff. She might be doing the same thing, who knows. You might regret it if you found out she did like you but she's moved on or something. If you tell her and she never talks to you again, then that shows what type of best friend you had. Just tell her dude.(: Good luck! :D
