Do you always become infatuated with a new partner?

It's stupid to have feelings this strong for someone I met not too long ago. I'm wondering though if infatuation is always part of the "process" or just in some cases? I've heard that relationships where both persons are infatuated at the beginning are more likely to fail. Is that true? We are both infatuated and i'm so worried that things will fail after infatuation fades for both of us, how can I or we work on this?
