i mean your friend told her already so why are u embarrassed i mean like your crush already knows like if your crush knows and is not being rude about it why are u embarrassed?
don't worry. If she heard and says she doesn't like you then just say: BBY HOW COULD YOU? OMG WE ARE BREAKING UP then run out and deal with your embarassment for the rest of your life. :> I'm sorry do not do that.
