I'm greatly infatuated by this girl and she affected me?

I'm greatly infatuated by this girl, I think she she the most beautiful girl in the world and everything she does is just perfect, and she is from this certain place, now, when I meet new friends I would tell them I'm from this place where the girl is from, even though I'm not, now I think of this place as superior place of the world, and sometimes I check out her social networking site and see her photos and I saw some pictures with that girl and her mother together, now her mother is ugly but I still think that her mother is superior, why is that?
