Sound like she likes everybody she hasent been with yet. Seem to me form all my experience girls like to date one guy and when they have succeded at that goal they move on to each friend just to see if they can do it. The fact that your friend and all of his family dose not like it probaly fuels the hole Idea of you two seeing each other. I have seen it a thousand time and expericed a couple. Dude she is not worht a friendship there are a million fish in the see dont catch the one with a millions hooks in it.
