Fortune teller? Would you believe one?

I wen't to see a fortune teller for fun. She told me about how my boyfriend at the time was foolish and more about him. It was all true. She said stuff about my family and I just found it recognizably true! I wanna see her again. But.. should I? I somewhat wanna see what she has to say about the guy I'm talking to now. Should I believe in her? Otherwise, to all the people out there who argue that they are fakes, and money suckers... How did she know all this? o.o
