Why do I know all these things about them?

Iately I've been able to find out things about a lot of women. It first started with this girl I met, we chill for a day and already I knew she was bi and she was promiscuous. She wasn't dressed like a slut and she was very innocent, but for some reason I didn't buy it. I found out that she was in fact one. The same day I found out she somehow knew and deleted me off her facebook. I'm not saying it's a gift, but I think me knowing to much about a girl with knowing her for little time is scaring them away.
