Some questions about women (girls only please)?

I have an "almost" female friend. Well, we're not acquaintances and not friends either. But anyhow, why is it that she wants to know/is curious about my friends/family and everyone else I know??? She even remembers everything I say even the smallest little insignificant things??? I also caught her googleing everyone I know online. Is she like investigating me or something bec it's really freakin' me out!!! She's also too secretive.
